Two solid ofequal mass
This is a multiple choice question. I need help as to arrive at the correct answer:
Two solids P and Q of equal mass are heated to the same temperature and dropped simultaneously into two identical containers X and Y containing equal volumes of water at room temperature. The temperature of X will rise higher than that of Y only if the
A. volume of P is greater than that of Q
B. specific heat capacity of P is higher than that of Q
C. density of P is greater than that of Q
D. density of P lower than that of Q
E. specific heat capacity of P is lower than that of Q.
Please explain and give reason for your answer. Any help will be appreciated greatly. Thanks!

P & Q start at same temperature (above the temperature of X, Y and the room) and have the same mass but are not guaranteed to share other properties. X & Y start with the same amount of water at the same temperature.
But if X + P finishes with a higher temperature than Y + Q, then X +P must have more heat than Y + Q. So P must have more heat than Q. So P must have a higher specific heat capacity than Q.
