Answer 1

May be composite number

Answer 2

Option D is correct.

• Let us discuss why the other options are incorrect.
• 1 is not a composite number because it has only one factor which is itself, while composite numbers have more than 2 factors thus option A will be an incorrect option.
• 1 is also not an even number because it is not a multiple of 2 hence option B is also incorrect.
• 1 is not a prime number because it has only one factor which is itself, while all the prime numbers have 2 factors i.e. 1 and themselves thus option C will be an incorrect option.
