The correct answer is A Energy leaves the iron bar and enters the wood until the temperature are equal.

Explanation:

According to the law of conservation of energy or the first law thermodynamics energy neither be created nor destroyed, energy is transferred from one form to another form.

Here iron bar is placed in wood block energy is transferred from iron bar to wood until the temperatures are equal.
