Select the most appropriate meaning of the given idiom.

Vis-a-vis

In relation to 

The correct answer is In relation to. The idiom "vis-à-vis" literally means "face to face" in French, but it is used in English to mean "in relation to" or "compared to." For example, you might say "The company's profits vis-à-vis its competitors are very strong."

The other options are incorrect. "The other way round" is the meaning of the idiom "the other side of the coin." "To complete" is the meaning of the idiom "to finish." "A complicated problem" is not an idiom.
