For the change, \( \mathrm{C}_{\text {diamond }} \longrightarrow \mathrm{C}_{\text {graphite }} ; \Delta H=-1.89 \mathrm{~kJ} \), if \( 6 \mathrm{~g} \) of diamond and \( 6 \mathrm{~g} \) of graphite are separately burnt to yield \( \mathrm{CO}_{2} \) the heat liberated in first case is:
(A) lèss than in the second case by \( 1.89 \mathrm{~kJ} \)
(B) less than in the second case by \( 11.34 \mathrm{~kJ} \)
(C) less than in the second case by \( 14.34 \mathrm{~kJ} \)
(D) more than in the second case by \( 0.945 \mathrm{~kJ} \)
