Answer 2

If the amplitudes of two waves have the same sign either both positive or both negative, they will add together to form a wave with a larger amplitude. This is called constructive interference.

If the two amplitudes have opposite signs, they will subtract to form a combined wave with a lower amplitude. This is called destructive interference.

This way we can say that two crest increase each other in constructive interference while they decrease each other in destructive interference.

So above statement must be FALSE
