Question

Fill in the blank with a suitable abstract noun:
He made the wrong choice due to his lack of (wise) .

• A. wise
• B. being wise
• C. wisdom
• D. having wise

Answer 1

The correct option is C wisdom

An abstract noun is a noun that cannot be seen or touched. It is an idea, quality or state.
'Wisdom' is an abstract noun form of the verb 'wise'; it refers to a quality, the capability of using knowledge and experience to make decisions. Hence option C is correct.
Option A is incorrect because 'wise' is a verb.
Option B is incorrect because 'being wise' is a verb phrase, where 'being' is an auxiliary (helping) verb and 'wise' is the main verb.
Option D is incorrect because it makes no sense. Also, 'having' and 'wise' are both verbs.
