Which of the following statement precisely explains why in bitcoin mining it is a Nash equilibrium for all miners to follow the longest chain rule (assuming that all miners have negligible computing powers compared to the global computing power)

A. When all other miners follow the longest chain rule, it is better to follow the longest chain rule too

B. When all other miners do not follow the longest chain rule, it is better to not follow the longest chain rule either

C. When all other miners follow the longest chain rule, it is better to not follow the longest chain rule

D. When all other miners do not follow the longest chain rule, it is better to follow the longest chain rule
