139372 Body A of mass $2 \mathrm{~kg}$ and another body $B$ of mass $4 \mathrm{~kg}$ and of same material are kept in the same sunshine for some interval of time. If the rise in temperature is equal for both the bodies, then which one among the following in this regard is correct?

1 Heat absorbed by B is double because its mass is double
2 Heat absorbed by A is double because its mass is half
3 Heat absorbed by both $\mathrm{A}$ and $\mathrm{B}$ is equal because the quantity of heat absorbed does not depend upon mass
