You are absolutely correct with the bond enthalpy Sir! My only guess it is not A is that after the removal of the first hydrogen the next H that is going to be removed from the resulting SiH3 will require slightly different energy as the chemical environment is different... so you need to break all bonds simultaneously to get the AVERAGE BOND enthalpy

Thank you so much, a funny chem teacher
