Answer: Option (B) is the correct answer.
Explanation:
A chemical reaction in which products can be changed back into the reactants is known as a reversible reaction.
For example,
On the other hand, a chemical reaction in which products are not changed back into the reactants then it is known as an irreversible reaction.
For example,
Thus, we can conclude that there are some reactions, however, that can return to their original forms. These reactions are called reversible.

The Law of Multiple Proportions states that if 2 elements form more than one compound between them, if the mass of one of the elements is fixed, the masses of the other element will be in a ratio of small whole numbers.
In this case, the two elements are Fe and Cl, and the 2 compounds are X and Y. Let us fix the mass of Fe in 1.00 g and analyze what happens with the masses of Cl.
For X:
For Y:
The ratio mCl in X/mCl in Y is 1.27g/1.91g = 0.664 ≅ 2/3. This is a ratio of small whole numbers, which proves the Law of Multiple Proportions.
