The correct answer is option (E):
Disapproval
The correct answer is disapproval.
The word "approbation" means approval or praise. It signifies a positive feeling or expression of endorsement. An antonym, by definition, is a word that means the opposite.
Looking at the options:
* Disguise: Refers to concealing or hiding something, which doesn't directly relate to approval.
* Corruption: Implies dishonesty or moral decay, a concept separate from approval.
* Treachery: Means betrayal of trust, again, not the opposite of approval.
* Permanent: Signifies lasting or enduring, which is unrelated to the concept of approval.
* Disapproval: Represents a negative sentiment, the act of not approving or expressing condemnation.
Therefore, "disapproval" is the closest antonym to "approbation" as it directly represents the opposite feeling or action.
