Which one of the followings is correct?

The correct option is:

c) "She was bored in the class."

Explanation:

a) "The woman which works here is from Japan." - The correct relative pronoun to use for people is "who," not "which." It should be "The woman who works here is from Japan."

b) "She is married with a dentist." - The correct preposition to use after "married" is "to," not "with." It should be "She is married to a dentist."

d) "Every students like the teacher." - The correct form is "Every student likes the teacher." The word "student" should be singular when used with "every," and "like" should be changed to "likes" to match the singular subject.

We use to, not with, after get married + direct object and be married + direct object:

• She got married to someone she met at college.
• She’s married to someone she met at college.

Not: She got married with someone … or She’s married with someone …
