Answer: C. Scalene.
Step-by-step explanation: An equilateral triangle is a triangle with all three sides that are the same. An isosceles triangle is a triangle with two sides that are the same, but one side that is different. A scalene triangle is a triangle with all three sides that are different. This triangle has three side lengths that are different, which means it's a scalene triangle.
