Selected Answer: A

Option C suggests setting the 24 Mbps rates to Mandatory. However, setting the 24 Mbps rates to Mandatory would require all clients to support and use 24 Mbps for data transmission, which might not be feasible or desirable in all situations. In a typical scenario, it's more common to set data rates as Supported rather than Mandatory. This gives the network more flexibility and allows clients to use the best available data rate based on their capabilities and the conditions of the wireless environment. Therefore, setting the 24 Mbps rates to Supported would allow multicast broadcast to be sent over 24 Mbps without forcing all clients to use it exclusively, making it a more practical choice.

Its a multicast question, ignore the rest, as we know, multicast is delivered on the highest mandatory data rate, if 24Mbps is made mandatory, then it will go over at 24Mbps.
