Solution

The correct option is A 5.8 cm
Steps of construction:
Step 1: Draw line segment AB = 6.5 cm.
Step 2: At A, construct $∠ A$ = 45°.
Step 3: At B, construct $∠ B$ = 60°.
Step 4: Mark the point of intersection as C.

From the above construction, measure the length of AC using ruler.
AC = 5.8 cm
