The correct answer is D. playing.
Rahul is a cricketer who is known for his batting skills. He is a very good player and can score a lot of runs. If he is playing well, then India has a good chance of winning the match.
The other options are not correct because they do not describe Rahul’s current state. Option A, plays, is in the present tense, but Rahul is not currently playing. Option B, played, is in the past tense, but Rahul is not currently playing and he has not played in the past. Option C, play, is in the plural form, but Rahul is a single person.
Therefore, the correct answer is D. playing.
