Answer 1

1)

The answer is option a.

An algorithm is sequence of instructions that solve a particular problem.

2)

The answer is option c.

The program control is the order in which the series of statements are executed.

It is basically about how a program makes decisions and executes the statements.

3)

The answer is option d.

A Pseudocode is a general english language description of the steps in an algorithm.

This is mainly used and developed for the purpose of human reading.

4)

The answer is option d.

A Pseudocode is a general english language description of the steps in an algorithm.

This is mainly used and developed for the purpose of human reading.
