The 2.4 GHz band is more likely to experience signal interference due to several factors. Firstly, this frequency band is used by a variety of devices and technologies beyond Wi-Fi, including microwave ovens, Bluetooth devices, and cordless phones. As a result, the 2.4 GHz band tends to be more crowded, which can lead to overlapping signals and increased interference from these other devices.

Additionally, the 2.4 GHz frequency has a longer range compared to 5 GHz, which means that its signals can penetrate walls and other obstacles more effectively, but this also makes the 2.4 GHz band more susceptible to interference from various sources, especially in densely populated areas where many networks might overlap.

The 5 GHz band, on the other hand, typically experiences less interference because it has fewer devices operating within that frequency range and offers more non-overlapping channels. This allows networks on the 5 GHz band to operate with less interference, making it a preferred option for environments where higher performance and reduced signal degradation are needed. Thus, the selection of the 2.4 GHz band is likely to encounter more interference, making it the correct answer to the question.
