Solution

The correct option is C XY+Z
If it is mass A
Y2Z
Reactant R=60×8.5=10meV
Product P=2×30×5=300meV
ΔE=210meV
Therefore Endothermic
If it was C
W2Y
R=120×75=900meV
P=2×60×8.5=1020meV
ΔE=120meV
Therefore Exothermic
If it was D
XY+Z
R=90×8=720meVP=60×8.5+30×5=66.0meV
ΔE=60meV
Therefore Endothermic
