∵ Equal volume of 1M HCl and 1M H2SO4 are used to neutralised by NaOH (dil.) separately.
HCl will give 1 mol of H+ ions per mole while.
Given,
H2SO4 will give 2 moles of H+ ions per mole.
Given:
1M HCl+ dil NaOH,ΔH=Xk.cal
1M H2SO4+ dil NaOH,
ΔH=Y k.cal
∵H2SO4 provide 2 moles of H+ ions per mole of H2SO4
Therefore, 2X=Y
∴ X=

1

2

Y
Hence, option (b) is the correct answer.
