In the question below fill the gap with the appropriate option :
Our principal and chairman of the occasion _____ just arrived
Answer Details
The appropriate option to fill the gap in the sentence would be "has". This is because "principal and chairman of the occasion" is a singular noun phrase, and therefore requires a singular verb form to agree with it in number. "Has" is the present tense form of the verb "have" in the third person singular (he/she/it), and is therefore the correct form to use in this context.
