If I wanted to write a sentence involving an item that refers to a whole category, should I use plural or singular form? If singular, should I add an article before that?
Is it a must that an article should be added before a singular countable noun in all circumstance?
E.g.
Apple is good for health
An apple is good for health
Apples are good for health
