Final answer:
The answer is c. BIOS. BIOS, unlike word processors, CAD, and DTP software, is not application software; it is a type of firmware that helps initialize hardware and load the operating system.
Step-by-step explanation:
The answer to the question 'Which of these is not application software?' is c. BIOS.
Application software refers to programs that are designed to perform specific tasks for users. Examples of application software include word processors, CAD (computer-aided design) software, and desktop publishing (DTP) software.
BIOS, on the other hand, stands for Basic Input/Output System and is a firmware that is stored on a computer's motherboard. It is responsible for initializing the computer hardware and starting the operating system, but it is not considered application software.

The BIOS (Basic Input Output System) is not an application software, unlike the other options provided which include a word processor, CAD (Computer-Aided Design), and DTP (Desktop Publishing) software. Application software refers to programs designed to perform specific tasks for users. In contrast, the BIOS is a type of firmware that is embedded on a computer's motherboard and is responsible for initializing hardware and loading the operating system during the boot-up process.
