Best answer
Correct option is (a) True

To elaborate: When heat is added at constant pressure the heat is used to increase temperature and increase volume or we can say does work. But when heat is added at constant volume the heat only increases temperature and volume remains the same (work = 0). So For the same rise in temperature at constant pressure we have to provide more heat.
