  1. A
    Both Statement I and Statement II are correct
  2. B
    Both Statement I and Statement II are incorrect

H$_2$S213
H$_2$Se232
H$_2$Te269

$\bullet$ The boiling points of these hybrids not exactly increases with increase in molar mass.

$\bullet$ H2O has maximum boiling point due to intermolecular hydrogen bonding.
