Explanation:

- Option 1: Theft

Theft involves taking someone’s property dishonestly, with the intent to permanently deprive the owner. Just finding something does not qualify unless there’s dishonest intent.

- Option 2: Robbery

Robbery is theft involving violence or threat of violence. Suman did not use force, so this option isn’t correct.

- Option 3: Cheating

Cheating involves deceiving someone to gain a wrongful advantage. There’s no element of deceit in just picking up a lost item.

- Option 4: Misappropriation

Misappropriation means dishonestly taking something found and keeping it, instead of trying to find the real owner. This fits what Suman did.
