ব্যাখ্যা
The correct answer is - খ) What she thinks is known to me.
Passive Voice of Complex Sentence
- Complex sentence-এ একটি clause একটি subject বা object হিসেবে ব্যবহৃত হয়।
- সুতরাং, active-এর object যদি একটি clause হয়, তাহলে passive-এর subject হিসেবে ঐ clauseটি ব্যবহৃত হবে।
- অথবা active-এর subject কোন clause হলে, passive-এর object হিসেবে তা ব্যবহৃত হয়।
- Clause-এর মধ্যকার verb-এর কোন পরিবর্তন হবে না।
Examples:
Act: I know what he thinks.

Other options
ক) What I think is known to her.
এখানে “What I think” বলা হয়েছে, অর্থাৎ “আমি কী ভাবি”—এটি মূল বাক্যের অর্থের সঙ্গে মেলে না।
গ) I am known what she thinks.
এটি ব্যাকরণগতভাবে ভুল। “I am known what…” এই রূপ ব্যবহার করা যায় না।
ঘ) What she thinks was known by me.
মূল বাক্য present tense (“know”) কিন্তু এখানে past tense (“was known”) ব্যবহার হয়েছে।
