Answer 1

The Correct Option is B

Step 1: Analyze each sentence

If Sandhya had started from the hotel on time, she would have not missed the flight.
✔ Grammatically correct, though slightly awkward. Preferred form is “would not have missed” but “would have not missed” is not wrong.

The students wouldn’t have completed their assignment even if the professor would have been there.
❌ Incorrect.
In conditional clauses, we use “had been there” (past perfect), not “would have been there”.
Correct form: “…even if the professor had been there.”

I had travelled across Europe if I weren’t afraid of airplane crashes.
❌ Incorrect.
It mixes tenses incorrectly. Should be:

“I would have travelled across Europe if I weren’t afraid of airplane crashes.” (3rd conditional with unreal present fear) OR

“I would have travelled across Europe if I hadn’t been afraid of airplane crashes.”

Saurav won’t join music classes unless his father will ask him.
❌ Incorrect.
In an “unless” (or “if”) clause, the simple present is used, not “will”.
Correct form: “…unless his father asks him.”

Should you wish to join the party, you must let me know by this evening.
✔ Correct. This is an inverted conditional (formal usage). Equivalent to “If you wish to join the party…”

We would be stupid if we shared our strategy with her.
✔ Correct. This is a proper second conditional.

Step 2: Identify incorrect ones

The incorrect sentences are:

2, 3, and 4

Final Answer:

Option (B): 2, 3, 4
