Answer 2

Answer:

The correct answer is option(d)

d) Underscore(_)

Explanation:

• Identifiers are the valid literals that can be used by the programmer for naming the variables, constants, functions, etc.
• These identifiers should be selected in such a way that they do not clash with the pre-defined keywords of language.
• One of the rules of creating the identifier is that the name of the identifier cannot start with any special character except underscore(_)
• There are some conventions of naming identifiers.
• For example The name of a variable should always start with a lower case letter and the Function name starts with a capital letter.
• But these are just conventions not rules.

For example:

int #var;

This is invalid

But

int _var;

This is valid.
