Change Sets are a point-and-click tool for migrating metadata between related Salesforce orgs, such as from a sandbox to a production org.
Option C: Deployment is done in a one-way, single transaction.
Correct.
Change sets are deployed in a one-way direction from the source org to the destination org.
The deployment occurs in a single transaction. If any component fails to deploy, the entire deployment is rolled back.
Before deploying a change set, you must set up a deployment connection between the source and destination orgs.
This connection is established through the Setup menu under Deployment Connections.
Change sets can only be sent between orgs that are affiliated, such as a sandbox and its production org, or sandboxes that are clones of the same production org.
They cannot be used between unrelated orgs.
Change sets can deploy the metadata of custom settings (the definition), but not the actual data stored within them.
To move custom settings data, you must use a data migration tool like Data Loader.
Change sets are designed to transfer metadata components, not data records.
To transfer data records, use tools like Data Loader or Data Import Wizard.

Conclusion:
The three characteristics of change set deployments are C, D, and E.

To address the view state limit error caused by loading over 10,000 records in a Visualforce page, the developer should implement pagination with a StandardSetController.
StandardSetController: This controller allows developers to easily paginate large sets of records in Visualforce pages.
"A StandardSetController object contains a reference to a list of records with pagination support, similar to the display in a list view."
- Apex Developer Guide: StandardSetController Class
Benefits:
Efficient Data Handling: It retrieves only a subset of records at a time, reducing the amount of data held in view state.
Built-in Pagination: Provides methods to navigate through pages of records (next, previous, etc.).
View State Limit: Visualforce pages have a view state limit of 170KB. Loading all records at once exceeds this limit.
"To optimize your Visualforce pages, minimize your use of view state. The view state of a Visualforce page is limited to 170KB."
- Visualforce Developer Guide: View State in Visualforce Pages
Why Not Other Options:
A . Implement pagination with an OffsetController: There's no standard OffsetController in Visualforce. Implementing custom pagination with offsets is less efficient and can be complex.
B . Use JavaScript remoting with SOQL Offset: While JavaScript remoting can reduce view state size, using SOQL OFFSET is not efficient for large offsets (over 2,000 records).
"When using OFFSET with a large number of records, performance degrades significantly."
- SOQL and SOSL Reference: OFFSET Clause
D . Use lazy loading and a transient List variable: Lazy loading can help, but it doesn't solve the issue of handling large datasets efficiently. Transient variables reduce view state but do not manage data retrieval or pagination.
Conclusion: Implementing pagination with a StandardSetController is the recommended solution to handle large datasets efficiently in Visualforce pages and prevent view state limit errors.
