C. A clause has a subject and a verb, but a phrase does not.

In Grammar, a clause is a set of words (that are related to each other) that contains a subject and its corresponding verb. A clause by itself is a group of words, that express a complete idea. Clauses usually are short, simple sentences. Whereas a phrase doesn't have both a subject and a verb. Hence, clauses are a group of words, that could state ideas independently, as separate sentences having a subject and predicate.

Explanation:

the second option.is correct

either a donut or a sphere or a pancake or a flat sphere. it depends on where the vertical line is.

if the line goes through the center of the circle and is perpendicular to a diameter containing the center, then you get a flat circle.

if the line and the diameter of a the circle meet in the center of the diameter and at an angle, you get a pancake.

if the line is on the circumference of the circle and is at right angles   to the circle you get a ring.

if the line contains the diameter, you get a sphere.

the the line is parallel to the diameter and touches the circumference, you get a donut.
