answer b (0.73)

Step-by-step explanation:

"Triple" means to increase in size by a factor of 3.  

Thus, B = (1 + r)^2 becomes

3 = (1 + r)^2.  Our task is to determine the value of r, the annual interest rate.

Taking the square root of both sides, we get

√3 = 1 + r, which yields √3 - 1 = r.

This is approx. 1.732 - 1.000, or 0.732.  Answer b) is closest.
