Complete answer: In the given question, we have to find out the plural form of the given noun ‘fish'. A singular noun names one person, place, thing, or idea, while a plural noun names more than one person, place, thing, or idea. There are a few basic rules to remember when it comes to turning a singular noun into a plural noun. 1. Most singular nouns need an ‘s’ at the end to become plural. For example, there's one dog (singular), but three dogs (plural).
Now, let us examine all the given options to find out the correct answer :
Option ‘a’ is Fishens. It is nor a word and doesn’t exist in the dictionary. This word has no meaning.
Option ‘b’ is Fish. It is the singular noun. A fish is a limbless cold-blooded vertebrate animal with gills and fins living wholly in water.
Option ‘c’ is Fishes. It is the correct plural form of the word ‘fish’ and is used to refer to many or a group of fishes.
Option ‘d’ is Fishe's. It is an incorrect option and an inappropriate word.
Hence, option ‘c’ is the correct option.

Note: If the singular noun ends in ‑s, -ss, -sh, -ch, -x, or -z, add ‑es to the end to make it plural. In some cases, singular nouns ending in -s or -z, require that you double the -s or -z before adding the -es for pluralization. eg: gasses.
