Answer 2

Answer:

B

Explanation:

Convection occurs when particles carry heat and transfer to other particles. As the solids are tightly packed, convection cannot occur.

Radiation requires no medium and heat transferred through radiation will get obstructed and absorbed by the solid, however, there are exceptions to these.

This leaves us with only one option, which is conduction. Conduction occurs only when particles are in touch with each other. Thus, this is the answer.
