Consider the following statements:

I. If a and b are composite numbers, then a + b is always composite.

II. Zero is a natural number but not a whole number.

Which of the above statements is/are correct from the options given below:

I only

II only

Both I and II

Neither I nor II

✅ Correct Option: 4

Statement I fails for $a = 9$ and $b = 4$ , both composite, since $9 + 4 = 13$ is prime.

Statement II is reversed: zero is a whole number but not a natural number.

So neither statement is correct.
