Sachin has bitten of more than he can chew. A. is always hungry B. is trying to do too much C. is very greedy D. has little regard for others

The correct answer is B. is trying to do too much.

The idiom “to bite off more than you can chew” means to attempt something that is too difficult or challenging for you. In this case, Sachin is trying to do too much, and he is likely to fail if he does not take on a more manageable workload.

Option C is incorrect because it is not a common meaning of the idiom, and it does not make sense in the context of the question. Option D is incorrect because it is not a common meaning of the idiom, and it does not make sense in the context of the question.
