When would you bond multiple 20MHz wide 802.11 channels?

When would you bond multiple 20MHz wide 802.11 channels?
A . To decrease the Signal to Noise Ratio (SNR)
B. To increase throughput between the client and AP
C. To provision highly available AP groups
D. To utilize high gain omni-directional antennas

Answer: B

Explanation:

Bonding multiple 20MHz wide 802.11 channels is a technique to create a wider bandwidth channel that supports higher data rate transmissions. It can increase the throughput between the client and AP by using more spectrum resources and reducing interference.
