Is Comb of banana a correct Collective Noun?

Here's why:

* Collective nouns refer to a group of similar things. Examples include: flock (birds), herd (animals), school (fish).

* Bananas are not typically grouped in a "comb" formation. The most common collective noun for bananas would be bunch or hand.

You could use "bunch of bananas" or "hand of bananas" to refer to a group of bananas.
