## Step 1The problem is asking us to identify the correct statement that accurately describes the differences between a cellular phone and a landline phone in terms of how they transmit signals.## Step 2A cellular phone uses radio waves to transmit signals. This is because cellular phones are mobile devices that need to communicate over long distances, and radio waves can travel long distances.## Step 3On the other hand, a landline phone uses electrical energy to transmit signals. This is because landline phones are connected to a physical network of wires, and the signals are transmitted through these wires using electrical energy.## Step 4The other options are incorrect because they either incorrectly describe the energy sources used by cellular and landline phones or incorrectly describe the transmission methods.
