Hi P5G,

I think your answer cannot be accepted as the sentence sounds a little odd.
Let's wait for the others to reply to double confirm.

Best Regards!

From the foodweb, A is the food producer. B is a herbivore while C is a omnivore.
C (a predator) preys on B (a prey).
Eating plants cannot be considered as a predator. So B is not a predator.
So answer is (2) - C only.

Hi Tang,

It is not necessary that 'A' must be a food producer. It can be a prey too.

Best Regards.
