The correct answer is: A. Sriram asked me in surprise if I believed all this.
The sentence “And you believe all this ?” asked Sriram, in surprise. can be paraphrased as “Sriram asked me in surprise if I believed all this.” This is because the word “surprise” indicates that Sriram was not expecting me to believe all of what he had just said. The word “asked” indicates that Sriram was seeking information from me, and the word “if” indicates that he was not sure of the answer.
The other options are incorrect because they do not accurately reflect the meaning of the sentence. Option B is incorrect because it suggests that Sriram was
not surprised, but rather in disbelief. Option C is incorrect because it suggests that Sriram was not asking me a question, but rather making a statement. Option D is incorrect because it suggests that Sriram was not surprised, but rather amazed.
