The correct option is A One cannot change one's personality or character.
A proverb is a short saying that states a general truth or advice.
They're popular as they are told and retold through generations,
incorporated in books and stories that grandparents narrate to children.
Proverbs have a deeper meaning than the one you perceive at first. The
given proverb is a general truth, about a leopard that can't change its
spots, but it has a deeper meaning. The spots on the coat of a leopard are a part of it, they've been
there since birth. The same way, the personality/character of a person
is so deeply rooted that it cannot be changed, hence option B is
correct. Option A is a general statement and options C and D are
baseless statements, hence none of them provide the meaning of the
proverb and options A, C and D are incorrect.
