BIncrease the signal strength
CMove the access point
DChange the broadcast channel

Explanation

Microwave ovens operate on the 2.4 GHz frequency band, which directly overlaps with 802.11b/g/n Wi-Fi signals. When a microwave is in use, it generates strong electromagnetic interference that disrupts nearby wireless signals, causing the intermittent connectivity reported by employees. Moving the access point away from the microwave eliminates the source of interference. The other options do not address the root cause: disabling SSID broadcast affects discoverability, not interference; increasing signal strength may marginally help but won't eliminate microwave interference; and changing the broadcast channel won't help because the entire 2.4 GHz band is affected by the microwave.
