The correct answer is D. Vissu said they passed by a beautiful lake when they went on a trip to Goa.
The sentence “Vissu said, ‘We passed by a beautiful lake when we went on a trip to Goa'” is in the past tense. This means that the event of passing by the lake happened before the time of speaking. The verb “pass” is conjugated in the simple past tense, which is used to talk about events that happened at a specific time in the past. The pronoun “we” indicates that more than one person was involved in the event. The prepositional phrase “when we went on a trip to Goa” provides more information about the time and place of the event.
The other options are incorrect because they use verbs that are not in the past tense. Option A uses the past perfect tense, which is used to talk about events that happened before another event in the past. Option B uses the present perfect tense, which is used to talk about events that have happened or are still happening at the time of speaking. Option C uses the past participle “passed” as an adjective, which is incorrect because the verb “pass” is not transitive in this sentence.
