`H_(2)(g) + 1/2O_(2)(g) rarr H_(2)O (l) , BE (H - H) = x_(1) , BE (O = O) = x_(2) , BE(O-H) = x_(3)`
Latent heat of vaporization of liquid water into water vapour `= x_4` then `Delta H_(f)` (heat of formation of liquid water) is:

A

`x_(1) + x_(2)/2-x_(3) + x_(4)`

B

`2x_(3) - x_(1) - x_(2)/2 - x_(4)`

C

`x_(1) + x_(2)/2 - 2x_(3) -x_(4)`

D

`x_(1) + x_(2)/2 - 2x_(3) + x_(4)`
