Fill in the blanks with the most appropriate option:-

The society members accused him ………misbehaving with his neighbors.

of

The most appropriate option to fill in the blanks is of.

The sentence is about the society members' accusation of the man for misbehaving with his neighbors. The preposition "of" is used to indicate the cause or reason for something. It is the most appropriate preposition to use in this context, as it describes the reason why the society members accused the man.

The other options are not as appropriate:

• For can be used to indicate the purpose of something. It is not accurate to use "for" in this context, as the society members did not accuse the man with the purpose of misbehaving with his neighbors.
• On can be used to indicate the location of something. It is not accurate to use "on" in this context, as the society members did not accuse the man on the location of misbehaving with his neighbors.
• Against can be used to indicate opposition to something. It is not as appropriate as "of", as it does not convey the same sense of causation.
