Could anyone confirm with me a possible error on WikiJob’s Numerical Test 1 Question 1?

The answer for this question worked out to be C: Y2-Y3

with the following methods:

1 - (100 / 95) * 100 = -5.26%

1 - (95 / 90) * 100 = -5.56%

1 (90 / 85) * 100 = - 5.88%

I suspect the answers could be wrongly worked out. Can anyone confirm this?
