The correct answer is C. Interference. Many cordless phones operate on the 2.4 GHz frequency band, which overlaps with 802.11b/g/n Wi-Fi. When the phone transmits, it competes for the same radio frequencies as the wireless network, causing RF (radio frequency) interference that degrades the wireless signal. This is…

Explanation

Many cordless phones operate on the 2.4 GHz frequency band, which overlaps with 802.11b/g/n Wi-Fi. When the phone transmits, it competes for the same radio frequencies as the wireless network, causing RF (radio frequency) interference that degrades the wireless signal. This is a classic real-world example of co-channel or adjacent-channel interference from a non-Wi-Fi device. Crosstalk occurs between physical copper wire pairs, not wireless signals. Signal strength latency and bouncing signal are not standard networking terms for this scenario.
