Oracle APEX is a low-code development platform that enables you to build database-centric web applications using only a web browser. Oracle APEX has the following features:
Requires no additional client software. A web browser is the app development IDE: You can use any modern web browser to access the Oracle APEX development environment and build your applications.
You do not need to install or configure any additional software or tools on your client machine.
Is declarative. It requires no code generation: You can use declarative tools, visual editors, drag-and-drop components, and pre-built templates to define your application logic, user interface, security, and integration features. You do not need to write or generate any code for your applications.
The other options are incorrect because:
Performs the data processing in a middle-tier server: Oracle APEX performs the data processing in the database server. It uses SQL and PL/SQL to access and manipulate the data stored in the database. It does not rely on any middle-tier server or framework for data processing.
Requires developers to be proficient in Java, Python and other programming languages: Oracle APEX does not require developers to be proficient in Java, Python or other programming languages. It uses SQL and PL/SQL as the primarylanguages for data processing. It also supports HTML, CSS, JavaScript, and jQuery for user interface development.

Explanation
To migrate an APEX app between environments, such as from development to production, you need to consider three components that make up an APEX app:
Database objects: These are the tables, views, procedures, functions, packages, triggers, sequences, synonyms, and other schema objects that store or manipulate the data used by the app. You need to move these objects from the source schema to the target schema using tools such as SQL Developer, Data Pump Export/Import, or Data Workshop.
Images: These are the static files, such as images, CSS files, JavaScript files, or PDF files, that are used by the app for display or download purposes. You need to move these files from the source web server to the target web server using tools such as FTP, SCP, or File Explorer.
Application definition and all associated files: These are the metadata files that define the app components, such as pages, regions, items, buttons, processes, validations, computations, dynamic actions, shared components, and so on. You also need to include any supporting object definitions or data scripts that are used to create or populate database objects for the app. You need to move these files from the source APEX instance to the target APEX instance using tools such as App Builder Export/Import or One-click Remote Application Deployment.
