B.
A composite number must be an odd number.
C.

D.
A composite number may be an even number or an odd number.

Answer 1

The correct answer is:

D. A composite number may be an even number or an odd number.

Explanation:

• A composite number is a natural number greater than 1 that is not prime, meaning it has at least one positive divisor other than one and itself.
• Composite numbers can include both even numbers (like 4, 6, 8, etc.) and odd numbers (like 9, 15, 21, etc.).
• Therefore, option D is true.
