$90^circ$ 8 cm
a. acute scalene triangle
b. right scalene triangle
c. acute isosceles triangle
d. right equilateral triangle

Explanation:

Step1: Check for right angle

One angle is $90^\circ$, so it is a right triangle.

Step2: Check side lengths

All sides: $4\ \text{cm}$, $7\ \text{cm}$, $8\ \text{cm}$ are distinct, so it is scalene.

Step3: Match to options

Combine right and scalene to identify the correct option.

Answer:

B. right scalene triangle
