Out of the given options, choose the most appropriate one to fill in the blank.
The students _______ the task in less than ten minutes.

Correct option is C

The correct option to fill in the blank is (c) accomplished.
Explanation: The action “accomplished” is completed and refers to a past event. No helping verb is present, so simple past is the right choice.
Grammatical rule used: Simple past tense is used for completed actions when no auxiliary verb is present.
Rule in Hindi: जब कोई कार्य अतीत में हुआ और पूरा हो गया हो तथा सहायक क्रिया न हो, तो simple past tense का प्रयोग होता है।
Meanings and explanations of other options:
· (a) has accomplished: Incorrect – “students” is plural, and should take “have accomplished,” not “has.”
(गलत – 'students' plural subject है, इसके साथ 'has' नहीं 'have' आता है)
· (b) has accomplish: Incorrect – wrong verb form and tense structure.
(गलत – tense और verb form दोनों गलत हैं)
· (d) have accomplish: Incorrect – “accomplish” is base form, should be “have accomplished.”
(गलत – 'accomplish' की जगह 'accomplished' आना चाहिए)
