2. B. If you will have
3. C. If you want to (Correct answer)
4. D. No improvement

Correct Answer

Option C — If you want to

Detailed Solution & Explanation

The correct answer is If you want to.

Key Points

• In a conditional clause, English uses the present tense for future meaning — "if you want to", not "if you will catch".
• The sentence means *come quickly if it is your intention to catch the train*, so the natural completion is if you want to, with *catch the train* understood.
• "If you will catch the train" is ungrammatical here, since *will* is not used in the if-clause of a first conditional.

Additional Information

• The first conditional pattern is *if + present simple, … will + base verb*: "If you hurry, you will catch the train."
• *Will* may appear in an if-clause only when it expresses willingness or a request — "If you will wait a moment, I'll fetch it" — which is not the sense here.
• The other conditionals: zero (if + present, present) for general truths, second (if + past, would + base) for hypotheticals, third (if + past perfect, would have + participle) for unreal past.
• Ellipsis after *to* is idiomatic and correct — "if you want to" needs no repetition of the verb phrase.
