Choose the correct phrase from the given option and make a conditional sentence.
I could marry her if I _________ to.

Correct option is A

Correct sentence: I could marry her if I wanted to.
Rule: In conditional sentences, past simple ("wanted") is used with "could" for hypothetical situations.
Example:
· She could travel the world if she saved enough money.
Meanings of other options:
· (b) had wanted ❌ (Incorrect: "Had wanted" is used in third conditional, referring to past regrets.)
· (c) have wanted ❌ (Incorrect: "Have wanted" is present perfect, which does not fit here.)
· (d) want ❌ (Incorrect: "Want" is simple present, but we need past simple for a hypothetical situation.)
Thus, "wanted" is the correct answer. ✅
