Identify the segment in the sentence that contains a grammatical error.
I was fully convinced that she did not believe a word of that I had said.

Correct option is B

The segment containing the grammatical error is "of that I had said."
· The phrase "of that I had said" is incorrect because "that" is an incorrect relative pronoun in this context.
· The correct phrase should be "of what I had said."
Correct Sentence: I was fully convinced that she did not believe a word of what I had said.
Grammatical Rule Used:
· "What" is used as a relative pronoun to refer to something previously mentioned ( the words that were said).
· "That" is incorrect in this case because it does not function as a noun referring to previous statements.
Explanation in Hindi:
❌ गलत: "of that I had said."
✅ सही: "of what I had said."
· "What" का प्रयोग किसी चीज़ को संदर्भित करने के लिए किया जाता है, जैसे कि "जो कुछ मैंने कहा।"
· "That" यहाँ उपयुक्त नहीं है क्योंकि यह आवश्यक संदर्भ प्रदान नहीं करता।
