The circumference of a circle is calculated using the formula C = πd, where C is the circumference and d is the diameter.

Given that the diameter of the coin is 50 mm, we can substitute this value into the formula:

C = π * 50 mm

Using the approximation of 3.14 for π, the calculation becomes:

C = 3.14 * 50 mm = 157 mm

So, the circumference of the coin, to the nearest mm, is 157 mm. Therefore, the correct answer is B) 157 mm.
