Identify the right passive voice of 'It is impossible to do this'.
A Doing this is impossible.
B This is impossible to be done.
C The is must be done.
D This can't be done.
Solution
Correct Answer: Option B
Active Voice: "It is impossible to do this."
Structure: [It (subject)] + [is impossible (verb)] + [to do this (infinitive phrase)]।
Passive Voice Rule:
Active-এ infinitive (to do) থাকলে Passive-তে "to be + V3 (past participle)" হয়।
Example: "to do" → "to be done"।
Option Analysis:
A) "Doing this is impossible." এটি Gerund (doing) ব্যবহার করেছে, Passive Voice নয়।
B) "This is impossible to be done." ✅ সঠিক Passive Structure: "This (subject)" + "is impossible" + "to be done (passive infinitive)"।
C) "The is must be done." Grammatically Incorrect (অস্পষ্ট ও ভুল structure)।
D) "This can't be done." passive voice হলেও, তার মানে একটু ভিন্ন; এখানে 'can't' ব্যবহার করা হয়েছে, যা ‘অসম্ভব’ নয়, বরং ‘অক্ষম’ প্রকাশ করে।
