I'm not too sure why B is not the answer, because I thought that the particle velocity at P would be the highest, not at Q, so it's wrong.But apparently D is wrong. So I guess I have to questions: why is it D and why is it not B.

Thanks sooo much

In regard to a particle at P, ask yourself what is the particle doing at P. If the particle is moving at maximum velocity at P, what is the direction of motion?

Don’t really understand what you are trying to ask in the following quote:

This is a progressive wave, so particles within one wavelength cannot be in phase. They are moving at different velocity.

Ahh i get the second bit. Sorry but where exactly is the velocity/ KE of the particles highest in a wave?

Have you studied simple harmonic motion?

Highly recommend that you take a look at it first.

The particles in a wave are modelled to undergo simple harmonic motion to produce transverse or longitudinal wave motion.

Note that the particle at P will move down from the maximum displacement, so the particle is making a U-turn. It makes no sense that the particles at P can have maximum speed.
