**(c)**

Here, 2 , 3 and 6 are in parallel. So potential drop across them will be the same. As heat produced, , so maximum heat will be generated across 2 resistance. Similarly 4 and are also in parallel, so more heat will e generated across 4 . Now the effective circuit will become

Total resistance,

Current,

and

Power spent across 2 ,

Power spent across 4 ,

. Hence maximum heat is produced in 4 resistance.
