* Correct Syntax for SOSL Query:
* Option B uses SOSL (Salesforce Object Search Language) to find records where the phrase
'ACME' appears in any field across multiple objects (Contact and Lead).
* Syntax used in Option B:
List<List<SObject>> searchList = [FIND 'ACME' IN ALL FIELDS RETURNING Contact, Lead];
* This query retrieves a list of SObject lists, where each inner list contains the results for a specific object (e.g., Contact or Lead).
* Why not the other options?
* A. Option A:
* This uses SOQL (Salesforce Object Query Language), not SOSL. SOQL cannot search across multiple objects or fields. The syntax provided is invalid because SOQL doesn't support "multi-object WHERE conditions."
* C. Option C:
* The Map<SObject> syntax is incorrect for SOSL queries. SOSL queries return a List<List<SObject>>, not a Map<SObject>.
* D. Option D:
* The syntax List<SObject> for SOSL is incorrect. SOSL must return List<List<SObject>> since the results are grouped by object types.

* Why Use Static Resources andTest.loadData?
* C: Static resources allow you to define reusable test data (e.g., in a CSV file).
* D:Test.loadDatasimplifies loading bulk test data into test classes from static resources.
* Why Not Other Options?
* A: Using@isTest(seeAllData=true)violates test isolation principles and is discouraged.
* B:@isTest(isParallel=true)is used for parallel execution, not for creating test data.
