Final answer:
The correct answer is 'd) left', as the verb needs to match the main subject in number, which is singular ('The Chief guest'), and the sentence is indicating a completed action in the simple past tense.
Step-by-step explanation:
The question pertains to the correct form of the verb to use with the subject 'The Chief guest, with his wife'. In English grammar, the verb must agree with the main subject of the sentence. In this case, 'The Chief guest' is the main subject, and the phrase 'with his wife' is an additional information that does not change the number of the subject. Therefore, the correct form of the verb should be singular to match the singular subject 'The Chief guest'.
The correct answer is: left. This is because the sentence is in the simple past tense, indicating a completed action.
The option 'a) has left' is also grammatically correct, but it is in the present perfect tense, not the simple past.
