Solution

The correct option is B SnH4> GeH4> SiH4> CH4
Observe that H is attached to carbon group elements. None of them enough electronegativity to reflect as H-bonding

Thus, only molecular weight is the criteria.

From periodic table, size and weight in order Sn > Ge > Si > C

Thus molecular weight order is SnH4>GeH4>SiH4>CH4.

Boiling point also follows the same order. So, SnH4 has highest boiling point.
