Answered by admin @ 13/08/2021

a) Invalid

b) Valid

c) Valid

d) Valid

Explanation:

a) 5 Total

This is considered invalid as it has a space character in between.

Identifiers are names used to store variables/values. They can start with alphabets/underscores and cannot contain any special character [(space), %, #, @, !, &, etc] in them.

Since 5 Total has a space in between, it cannot be classified as an identifier.
