Show answer and explanation

Correct answer: (C) to handle certain hazards

Explanation

Renaming gives separate physical registers to unrelated values sharing an architectural register name. This removes false dependencies, namely write-after-read and write-after-write hazards, permitting more overlap. It does not remove a genuine read-after-write dependency. Thus C.
