'आबांना हल्ली सारखा विसर पडत असतो.'
- विशेषण उपयोगात आणून हे वाक्य कसे करता येईल ?

The correct answer is Option C (आबा हल्ली फार विसराळू झाले आहेत.).

Key Points:
• The key concept is sentence transformation using adjectives (विशेषण).
• The original sentence uses 'विसर पडत असतो', where 'विसर' acts as a noun phrase denoting forgetting.
• To convert this meaning into a sentence using an adjective, we must describe the subject 'आबा' directly. The Marathi adjective for someone who forgets often is 'विसराळू' (forgetful). Thus, 'आबा हल्ली फार विसराळू झाले आहेत' correctly uses the adjective.
• Options 1, 2, and 4 use verbs (विसरत) or abstract nouns (विस्मरण, विस्मृती) rather than adjectives.
• Key Takeaway: To describe a person who forgets frequently, the Marathi adjective 'विसराळू' (forgetful) is used.
