Asan did very well during the exam. He must have studied very hard

a) must study

b) should study

c)must have studied

d) should have studied

Explanation:-

Use of must:- we use must to express a very specific and strong point of view. We use modal must to express someone's opinion also.

  • And here, we used must to express a exact opinion of Asan's guardian that he must have studied very hard in his exam.

Use of should:- we use should to suggest or advice someone about some specific point. As same as must, should modal is also used to express someone's opinion.

  • But in our sentence, Asan's guardian didn't suggest or advice him, but expressed his exact point of view that he observed.
