c= varname@
d= none of these

Answer 1

Answer:

D .None of these. It is the correct identifier

Answer 2

Answer:

The correct option is d = none of these.

Explanation:

Rules for properly naming an identifier are as follows:

1. It should start with a letter. It cannot start with any digit or a special character.
2. The letter can be followed by a digit or an underscore.

The following are the given options:

a= $var-name

This is wrong because it starts with a $ sign which is not accepted.

b= VAR-123

This is wrong because it includes a ' - ' i.e. hyphen sign which is not accepted.

c= varname@

This is wrong because it includes a ' @ 'sign which is not allowed.

Therefore, the correct answer to this question is  d. none of these.
