B) a = 11.71 and b = 15.56 is the correct answer.

Answer:

The answer is B.

Step-by-step explanation:

As the sum of interior angles in a triangle is 180deg.

<C = 180-110-45 = 25deg.

Using sine rule, a/sinA = b/sinB = c/sinC

a=7*sin45deg/sin25deg = 11.71

b=7*sin110deg/sin25deg = 15.56

The answer is B.
