Answer:
Option C). cosB
Step-by-step explanation:
In the picture attached by sin rule sin A = 24/25 means
sin A = BC/AB = 24/25
Now for the same value or same ratio will be of cosine of angle B for which height of the triangle will become base of the triangle.
cos B = BC/AB = 24/25
Therefore option C) cos B is the answer.
