Charles feared that the big and scary dog would jump over the short metal fence." A comma should be added between?

Charles feared that the big and scary dog would jump over the short, metal fence.

Explanation:

A comma should be placed between the adjectives that describe the noun fence. The reason is that they are not joined by a coordinating conjunction as in the description about the dog: big and scary dog. As a result, since they appear in the form of list without any linking words, they must be separated by a comma.

answer: the first one

explanation:

explicitly is defined as “in a clear and detailed manner, leaving no room for confusion or doubt.” the rest are interpretive and not clearly proven leaving in fact possible “confusion or doubt” which explicitly, by definition cannot have.
