Biomechanics - Exercise and Sports Medicine. What is the half-life

This is a following sample question from a past midterm. The midterm is later this morning (11 am eastern time) so help would appreciated!

Question. A tendon with a maximum strain of 10% and a passive visco-elastic half-life of 5 minutes for both elongation and recovery from elongation is stretched by a load sufficient to cause it to rupture if left to creep indefinitely. However, it is not left under this load indefinitely, but for 10 minutes, after which it is unloaded for 5 minutes. How strained will be after this 10 minutes of stretching and 5 minutes of recovery.

a) 3.75%
b) 5%
c) 7.5%
d) it would have ruptured completely

I'm thinking the answer is c?
