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.

In an Employee form, the 'Commission' and 'Hire Date' fields are enabled only if the Job is 'Salesman'. This can be achieved by using Dynamic Actions in APEX. Dynamic Actions are declarative components that define client-side behavior without writing JavaScript code. You can create Dynamic Actions on items, buttons, or regions of a page by specifying an event, a condition, an action, and other properties. In this scenario, you can create a Dynamic Action on Job item with Change as event, Execute JavaScript Code as action, and use jQuery to enable or disable Commission and Hire Date fields based on Job value. Processing, Conditional SQL, and PL/SQL procedure are not features of APEX that can achieve this requirement without writing JavaScript code.
