Fill in the blank with the correct preposition: ‘He is capable ___ solving this problem.’

Explanation

The adjective ‘capable’ is conventionally followed by the preposition ‘of,’ as in ‘capable of solving this problem’ or ‘capable of great things.’ This fixed prepositional pairing is commonly tested alongside similar expressions like ‘incapable of’ and ‘aware of,’ all of which pair with ‘of’ rather than other prepositions.
