Water

Explanation:

Given the specific heat of oxygen is 918J/kg°C and the specific heat of water is 4181 J/kg°C.

Consider 1Kg mass of each substance.

Now 1 Kg of oxygen needs 918 J of energy to raise its temperature by 1°C

Also 1 Kg of water needs 4181 J of energy to raise its temperature by 1°C.

Clearly water recquires more energy when compared to oxygen.

Basically specific heat capacity is the amount of energy recquired to raise the temperature of a 1 kg body by 1°C.
