Answer:
A. To travel all the way around something.
Explanation:
The word "circumnavigate" is a verb that is a result of a prefix and a root word. By affixing the word "circum" to the root word "navigate", we get a new word "circumnavigate".
Now, reading into the meaning of the words "circum" and "navigate", we can infer that it means to move or revolve around something in a roundabout way. To navigate means to move around while "circum" means roundabout or around. Thus, we can safely assume that the word "circumnavigate" means to travel or go around all the way.
Thus, the correct answer is option A.
