Ancient :

The correct answer is B. Modern.

Ancient means belonging to the distant past, especially the period before the Middle Ages. Modern means belonging to the present or recent times.

Repulsion means a feeling of dislike or disgust. Disappear means to cease to exist or be visible. Departure means the act of leaving a place.

Ancient and modern are opposites. Ancient refers to the past, while modern refers to the present or recent times. Repulsion, disappear, and departure are all related to the idea of something ending or going away. However, only modern is related to the idea of something new or different.
