What role does branch prediction play in a modern CPU pipeline?

A. It maps virtual memory addresses to physical sectors
B. It guesses the outcome of an if-statement before it executes to keep the instruction pipeline full
C. It translates high-level code directly into binary
D. It determines the power voltage required for overclocking
