Answer options

• B. It uses the multicast routing table to perform the multicast forwarding function.
• C. It uses unicast routing information to perform the multicast forwarding function.
• D. It uses broadcast routing information to perform the multicast forwarding function.

Correct answer: C

Explanation

The correct answer is C because Protocol Independent Multicast (PIM) leverages unicast routing information to facilitate multicast forwarding. Options A, B, and D are incorrect as they either describe functionalities that are not part of PIM's operation or inaccurately represent the type of routing information used.
