The answer is #"option (3)"#

Explanation:

#"density "="mass"/"volume"#

Therefore,

The volume of the first body is

#v_1=36/9=4 "cc"#

The volume of the second body is

#v_2=48/d "cc"#

For equilibrium, the net force is the same

#"Net force" = "weight"- "weight of fluid displaced"#

#36g-4*1*g=48*g-48/d*1*g#

#36-4=48-48/d#

#48/d=16#

#d=48/16=3gcm^-3#

The answer is #"option (3)"#
