Which sentence correctly uses commas to separate coordinate adjectives?

Question

A The long winding, corridor is illuminated with oblong skylights.

B The long, winding, corridor is illuminated with oblong skylights.

C The long, winding corridor is illuminated with oblong skylights.

D The long winding corridor is illuminated with oblong, skylights.

Answer 1

Coordinate adjectives  here are long and winding. A misses the comma after long.  B includes  comma after

winding and that is incorrect. D does not include any comma after long. It is C that correctly uses comma separating two coordinate adjectives.

 

 

Answer 2

I agree that C is the correct answer.  another way to describe why c is correct and the others are wrong is that when there are more than one adjective, then a commas separates each adjective. However, whether there is a string of adjectives or just one, the adjective closest to the noun never has a comma separating it from the noun.
