Answer:

The coefficient of thermal expansion of material B is more than A

Explanation:

As we know that when we apply heat to a material it expands. The amount of expansion depends on the nature of the material. The amount of expansion depends on the coefficient of thermal expansion of the material.

If a material has high value of thermal expansion coefficient then it expands more.

here material A expands less and material B expands more because the pin which is made by material A becomes loosen, so the coefficient of thermal expansion of B is more than the coefficient of thermal expansion of A
