Solution

The correct option is A a-f, b-g, c-h, d-e
Thermal expansion depends upon dimension , nature of material and temperature rise
$α, β$ and $γ$ depends on material nature.
Bimetallic strip is used to make the balance wheel of watch.
Invar steel is used to make pendulum clock.
Therefore option(C).
