Chem mcq

Could someone pls explain this to me? Why are those values getting divided by (0.1 x 1000)? The answer is C

Q = MC ^ T (where q=heat energy change)
^ H= -Q/moles (where H=enthalpy change in J/mol)
0.1 moles of solution will react in this case.
You have to divide by 1000 once more to convert from J/mol to kJ/mol.
