The answer is #option (3)#

Explanation:

The equivalent weight of metal is

#="mass of metal "/ "mass of hydrogen " xx1.008#

The mass of metal #=1.2 g#

Volume of hydrogen is #=1.12l " at NTP"#

Mass of hydrogen is

#= " Volume of hydrogen at NTP (ml)" xx 0.000089#

#=1.12xx1000xx0.000089#

#=0.0997#

The equivalent of the metal is

#=2/0.0997xx1.008#

#=20.2g#

The answer is #option (3)#
