Answer 1

Answer:

A. if

It is a conditional statement, and "if" is used to introduce the condition(നിബന്ധനവയ്ക്കുന്ന) or hypothetical situation(ഊഹിക്കാവുന്നതായ).

• Form:  If + past perfect (had + past participle), would + have + past participle.
• "If I had known how much I would disappoint him (past perfect condition), I wouldn't have done it (hypothetical result in the past)."

Conditional form - ഒരു conditionന്റെ ഭാവി ഫലമായേക്കാവുന്ന ഒരു കാര്യത്തെക്കുറിച്ച് സംസാരിക്കാൻ ഈ ഫോം ഉപയോഗിക്കുന്നു. മിക്ക conditional sentence `if' അല്ലെങ്കിൽ `unless' എന്നതിൽ തുടങ്ങുന്നു. 

For example `If that happens, we'll be in big trouble' and `You don't have to come unless you want to.
