A monkey of mass `20kg` is holding a vertical rope. The rope will not break when a mass of `25kg` is suspended from it but will break it the mass exeeds `25kg` . What is the maximum acceleration with which the monkey can climb up along the rope? `(g=10m//s^(2))` .
A. `10m//s^(2)`
B. `25m//s^(2)`
C. `2.5m//s^(2)`
D. `5m//s^(2)`
