Question

Which sentence correctly uses commas to separate coordinate adjectives?
A.
The bright, sunny afternoon was perfect for a picnic.
B.
She wore a long, red silk dress to the event.
C.
The cold snowy morning made travel difficult.
D.
He adopted a playful small puppy from the shelter

Answer 1

A.

"Bright" and "sunny" are coordinate adjectives (you can say "bright and sunny afternoon" and they independently modify "afternoon"), so the comma is correct. The others either lack a needed comma (C and D) or break up a noun phrase that should stay together ("red silk dress" in B).
