Refer to the exhibit. A user reports show response time to a network administrator and suggests that there might be a problem with the WLAN. The user's laptop supports 802.11n in the 2.4 GHz band only. The network administrator finds the user on the Mobility Master (MM) and reviews the output shown in the exhibit. What can the network administrator conclude after analyzing the data?

A) Client health is low, and retried frames are high. It is possible there is high channel utilization.
B) Client health is low, but SNR is high. It is possible data in the dashboard is not accurate and needs to be updated.
C) The speed is good. Client health seems to be related to a problem with the client NIC.
D) The network is low because of low SNR. TX power must be increased in both the client and the AP.
