Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A - IV, B - I, C - II, D - III
| List-I | List-II | Explanation |
|---|---|---|
| A. He has already solved the puzzle. | IV. has already solved | Clue word: "already". Present perfect (has/have + past participle): an action completed by now, with its result in the present; "already" goes with this tense. |
| B. He solves his math sums regularly. | I. solves | Clue word: "regularly". Simple present: "regularly" shows a habit, an action done again and again. |
| C. He solved the puzzle yesterday. | II. solved | Clue word: "yesterday". Simple past: "yesterday" names a finished past time, and the present perfect is never used with such a word. |
| D. He has been solving tricky problems since his childhood. | III. has been solving | Clue word: "since". Present perfect continuous (has/have been + -ing): "since his childhood" gives the starting point of an action that has gone on up to now. |
Note: Sentence A on its own could also take "solves" or "solved"; it gets "has already solved" because the other three sentences need the other three forms.
