As per the law of conservation of energy:
C. The reaction system absorbs 22 kJ of energy from the surroundings
This law of energy states that the energy remains conserved its neither created nor destroyed. It remains conserved throughout the reaction.
when an amount of heat gets absorbed during the reaction from the surroundings this type of reaction is known as an endothermic reaction.
So, for fulfilling law of conservation, same amount of energy must be asborbed.
Thus, option C is correct.
