It is Specific Heat or Specific heat capacity. - but not specify heat.
The question needs to be corrected.
Heat energy required to increase the temperature of an object = mass * specific heat capacity * increase in temperature in °C
= heat capacity * increase in temperature in °C
Specific heat capacity is the energy required to increase the temperature of an object of unit mass by 1 °C.
If the specific heat is higher then the amount of heat energy required to increase the temperature of an object by 1°C is higher. So it takes a longer time to heat up, if the surroundings are supplying heat energy at a constant rate.
