Correct option is C
The correct direct speech is (c) Sobhit said, "I can speak more fluently than Rahul."
Rules of conversion (indirect → direct):
·
He (reported subject) reverts to the speaker’s
I.
· Modal
could in indirect often reflects the backshift of
can in direct; restoring direct speech recovers
can.
· Keep the degree adverb
more with adverb
fluently (not “fluentlier,” which is wrong; and not “most … than”).
·
Structure:
· Indirect:
X said that he could… → Direct:
X said, “I can …”.
·
Example:
She said that she could help → She said, “I can help.”
