She is standing . . . . . . . . her boyfriend.

Solution (By Examveda Team)

In the sentence "She is standing . . . . . . . . her boyfriend," the most appropriate preposition is "with". The preposition "with" is used to indicate being in the company of or in the presence of someone. In this context, it suggests that she is standing alongside or near her boyfriend, implying a sense of togetherness or companionship.

Option A: for – "For" is used to indicate purpose, reason, or benefit, and does not fit the context of standing next to or near someone.

Option B: by – "By" can mean near or next to, but it is more commonly used to indicate proximity in a more static or passive way, and may imply standing close to but not necessarily in direct company. It is less fitting than "with" in this context.

Option C: in – "In" indicates being inside or within something, which does not make sense for this context of standing next to someone.

Therefore, the correct preposition is "with", as it best conveys that she is standing in the company of her boyfriend.
