Correct Answer: Option A
Explanation

Stored instructions and data in a digital computer consist of "bits."

A bit is the smallest unit of information in a digital computer. It can be either a 0 or a 1. Bits are combined to form bytes, which are used to represent characters, numbers, and instructions.

Alphabets, numerals, and characters are all represented by bits in a digital computer. For example, the letter "A" can be represented by the bits 01000001, the number "1" can be represented by the bits 00000001, and the character "@" can be represented by the bits 01001000.

The instructions that a computer follows are also stored as bits. These instructions tell the computer what to do, such as add two numbers, print a message, or open a file.

Bits are the foundation of all data and instructions in a digital computer. Without bits, computers would not be able to function.
