Explanation:

• In the first option, parentheses are correctly used to provide additional information about the Industrial Revolution.
• In the second option, the em - dashes are misused as "and" is already a conjunction; em - dashes are for interruptions or emphasis, not for joining items with "and".
• In the third option, parentheses are misused; they should not be used to set off a main - clause element like this.
• In the fourth option, the comma before "and" is incorrect in a simple list of two items; no comma is needed.
