Which option must be placed between coordinated adjectives

The option that must be placed between coordinated adjectives is a comma.

For example:
- She wore a beautiful, elegant dress to the party.
- He is a tall, handsome man.
- The old, crumbling house was haunted.

When using coordinated adjectives, a comma (,) must be placed between the adjectives.

When using coordinated adjectives, it is essential to place a comma between them. This helps to clarify that the adjectives are separate and are not modifying each other. To determine whether adjectives are coordinated, you can try reordering them or inserting the word "and" between them. If the sentence still makes sense and the meaning is unchanged, the adjectives are coordinated. For example:

1. The small, red car.
- Reordered: The red, small car.
- "Small" and "red" are coordinated because both orders make sense and convey the same meaning.

2. The old wooden cabinet.
- Reordered: The wooden, old cabinet.
- "Old" and "wooden" are coordinated because both orders make sense and convey the same meaning.

By placing a comma between coordinated adjectives, you ensure that the reader understands that each adjective independently modifies the noun.
