Answer 2

Atmospheric effect  is not a source of the noise.

Atmospheric effect:

Due to absorption, dispersion, and reflection in the atmosphere, the Atmospheric Effect reduces the strength of solar energy.

Explanation for incorrect answer:

manufacture electrical system:

A company that creates products in the manufacturing business. so this is the wrong answer.

another communication signal:

This noise is caused by external sources that may arise in the communication medium or channel. So this is the wrong answer.
