C will be an answer.

Why C?

Sangram said:   9 years ago
I think b will be the answer because the heat transfer takes place in natural convection due to density difference.

Remo said:   7 years ago
B should be the correct answer.

Ajay said:   7 years ago
Density difference produced by temperature gradient is the right answer.

Rais said:   5 years ago
B is the right answer as density is the driving force.

Akhlaque Ahmad said:   4 years ago
None of these is right because option B is become right but in option B, the temperature gradient is produced due to density difference but density difference produced due to temperature gradient.
