Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (B) and (C) only
(A) The circles on the OMR sheet must be fill with a black ball pen. — Incorrect.
- The given sentence says “must be fill”.
- The passive after a modal is modal + be + past participle (V3).
- “Fill” is the base verb, and its V3 is “filled”.
- Correct form: The circles on the OMR sheet must be filled with a black ball pen.
(B) Somebody must have left the gate open. The goats are in the vegetable garden. — Correct.
- Must have + V3 shows a confident guess about the past.
(C) Cover the pickle jar tightly lest ants should get into it. — Correct.
- Lest ... should + base verb shows something we want to stop from happening.
(D) Meena could able to finish the jigsaw puzzle in ten minutes. — Incorrect.
- The given sentence says “could able to”.
- A modal like “could” needs a verb after it, and “able” is not a verb.
- For one success in the past, we use was able to.
- Correct form: Meena was able to finish the jigsaw puzzle in ten minutes.
