General Rules:
* Singular: Most country names are singular, even if they end in "-s" (like the United States).
* Plural: Some names are inherently plural, like the Netherlands.
* Context: The context of your writing can influence whether you use a singular or plural form.
Specific to India:
* "India" is a singular noun and should always be treated as such.
Example:
* Incorrect: The Indias are a diverse country.
* Correct: India is a diverse country.
Key Point: Even if "India" seems like it should be plural (due to the "s" at the end), it's treated as singular in English.
