Explanation:

Let’s break it down:

- Theft? Not really. Theft means taking someone’s property dishonestly without their consent. If the accused bought the watch and paid Rs.100, there was consent. That rules out theft.

- Criminal breach of trust? Nope. That would mean the accused was entrusted with property and then misused it. Here, there’s no trust betrayed—it’s just a sale.

- Criminal misappropriation? That’s about taking possession in a dishonest way, without any intention to return the property or pay for it. Again, the accused paid money, there’s no evidence of dishonesty.

- No offence This is a basic sale. Payment was made, so the transaction itself isn’t illegal—unless you have extra facts (like if the seller wasn’t the real owner), but nothing like that is mentioned here.
