Which do not represent loop
Literally, looping means repeating an action or sequence of actions as long as a given condition is true.
For options (a) to (d), we have:
(a): if-then-else:
if statements are used to test conditions; depending on the truth or falsity of the condition, only one block of code can be executed at once.
In summary, if statements are not loops
(b): switch statements
This is an alternate to if statements and can be used in place of if statements.
Hence, switch statements are not loops
(c) and (d): for and while:
The above represent loops, because they both involve repetition of operations until the condition is no longer satisfied.
