Lines e and f are parallel because their alternate exterior angle is congruent. Option C is correct.

Find the diagram attached;

The point where two lines meet is known as an angle.

From the given diagram, we can see that the angle of 75 degrees is at the top left corner is similar to the 75 degrees down right.

Hence we can conclude that lines e and f are parallel because their alternate exterior angle is congruent.
