My husband has studied only . . . . . . . S.S.C. A. till B. up to C. for D. since

The correct answer is B. up to.

The word “up to” is used to indicate a limit or boundary. In this case, it is used to indicate that the husband has only studied up to the level of S.S.C. This means that he has not studied beyond S.S.C.

The other options are not correct because they do not indicate a limit or boundary. The word “till” is used to indicate a point in time, while the word “for” is used to indicate a period of time. The word “since” is used to indicate a point in time from which something has happened.

Here are some examples of how the word “up to” can be used in other sentences:

• I will stay here up to 10 o’clock.
• I have been working on this project up to now.
• I have been a member of this club up to last year.
