जो विकारी शब्द नामाची व्याप्ति मर्यादित करतो त्यास ________ म्हणतात.

The correct answer is Option C (विशेषण).

Key Points:
• This is the standard grammatical definition of an Adjective (Visheshan) in Marathi.
• An adjective is a declinable (Vikari) word that provides special information about a noun and thereby limits its scope.
• For example, 'Dog' refers to all dogs. But 'Black Dog' limits the scope only to dogs that are black. Here 'Black' is the adjective.
• A pronoun (Sarvanam) replaces a noun, while a verb (Kriyapad) shows action.
• Key Takeaway: An adjective gives specific information about a noun and limits its application/scope.
