The correct answer is letter "A": factories often need fewer workers.

Explanation:

Automation is the introduction of machinery in manufacturing companies with the intention of mass-producing standardized goods in an attempt to reduce costs by using large lines of equipment instead of more human labor hand. While this represents an advantage for companies, it is a drawback for employees who see their job duties being handled to machines.

Automation is used in different industries such as utilities, defense, and information technology.
