Answer Key / Explanation : (c) -
(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.
