Complete the sentence by choosing the correct word given in the brackets.
A solar cell converts — (sound/light) energy to — (light/electrical) energy.

Explanation

To complete the sentence correctly, we need to analyze the function of a solar cell.

1. **Identify the type of energy a solar cell uses**: A solar cell is designed to capture energy from sunlight. The energy present in sunlight is known as light energy. Therefore, for the first blank (dash A), we will choose "light".

2. **Identify the type of energy a solar cell produces**: The primary function of a solar cell is to convert the captured light energy into another form of energy. In this case, the solar cell converts light energy into electrical energy. Thus, for the second blank (dash B), we will choose "electrical".

Putting it all together, the completed sentence is:
"A solar cell converts light energy to electrical energy."
