Correct option is D
✔️ Option (d)
already saw contains the error.
·
Explanation:
· “Have” is an auxiliary verb that forms the
present perfect tense, which must be followed by the
past participle (V3) form of the verb.
· “Saw” is the
simple past (V2) form, which is incorrect here.
· Correct form: “have seen”.
·
Grammatical rule used:
·
Present Perfect Tense: Subject + has/have + past participle (V3)
· ✦
Hindi Explanation: Present perfect tense में "has/have" के बाद क्रिया का तीसरा रूप (V3) प्रयोग होता है। इसलिए “have saw” गलत है, सही “have seen” है।
