Dear student.
The correct option is B.
In the given food chain, P depends on producers for their food, Q depends on P and R depends on Q.
Population of P will increase and R will decrease. This is due to the reason that, when X is introduced in the community, which feeds on Q, population of Q will reduce, this will affect both P and R. As Q feeds on P, and the population of Q is reducing, this will result in the increase in the population of P. The opposite is in the case of R, as it depends on Q for food, and Q is reducing, as a result of which R will also reduce.
Regards.
