MOVING

A. Taking
B. Toying
C. Shifting
D. Turning

Answer: Option C

Explanation:

Meanings of the given words:

Moving = means shifting one place to another.

Taking = the action or process of taking something.
Toying = consider (an idea or proposal) casually or indecisively.
Shifting = move or cause to move from one place to another, especially over a small distance.
Turning = a place where a road branches off from another.

For eg. "I was toying with the idea of writing a book"

So, Shifting is the correct answer. Because other words mostly related to particular objects but only shifting relates to every single object so shifting is correct answer.
