Your company hires you to troubleshoot their 802.11abgh-compliant, Wi-Fi-certified access point and wireless client devices. Subsequent to carrying out a site survey, you identify five neighboring 802.11b access points that belongs to your company; one on channel 1, three on channel 6, and one on channel 11. What is the most appropriate change that is recommended to best circumvent co-channel and adjacent channel interference?

C.
Configure Company’s access point to use 802.11a with dynamic frequency selection (DFS).
