Which best describes the relationship between the two triangles below?

A- Triangle M L N is similar to Triangle F G H because of the third angle theorem, Angle M is congruent to angle F, Angle L is congruent to angle G, and Angle N is congruent to angle H.

B- Triangle M L N may or may not be similar to Triangle F G H because the third angle is unknown.

C- Triangle M L N is similar to Triangle F G H because of the angle-angle criterion, Angle M is similar to angle F, Angle L is similar to angle G, and Angle N is similar to angle H.

D- Triangle M L N may or may not be similar to Triangle F G H because the side lengths are unknown.
