It is I who ... to blame.
Solution
Correct Answer: Option A
Relative Clause এ "who" এর পরে Verb নির্ধারণের নিয়ম:
"Who" যে Pronoun কে refer করে, সেই অনুযায়ী Verb বসে
এখানে "who" refers to "I", তাই "am" হবে
বাক্য বিশ্লেষণ:
It is I = Main Clause
who am to blame = Relative Clause
উদাহরণ:
- It is I who am responsible
- It is he who is working
- It is they who are singing
