The following sentence has been divided into parts. One of them may contain an error. Select the part that contains the error from the given options. If you don’t find any error, mark ‘No error’ as your answer.
In the future, humans had colonise Mars / and establish a thriving civilisation / on the red planet.

Correct option is A

✔️ Option (a) contains an error.
· Explanation:
· The verb "had colonise" is incorrect; it should be "will colonise" or "will have colonised" to match the future context. “Had” is past perfect and doesn't suit a future timeline.
· Grammatical rule used:
· When referring to future events, we use will + base verb (simple future) or will have + V3 (future perfect).
· Hindi Explanation: “In the future” भविष्य के समय को दर्शाता है, इसलिए “had colonise” (जो past perfect है) गलत है। यहां “will colonise” या “will have colonised” सही होगा।
· Meanings of other options:
· (b) – No tense or structure error; grammatically valid.
· (c) – Incorrect; error exists in (a).
· (d) – Correct prepositional phrase.
