Explanation:

- Removing ornaments from a dead body is not considered robbery. Robbery needs violence or threat to a living person.

- It's also not dacoity. Dacoity means armed robbery by a group of five or more people.

- The correct term is theft. According to Indian law (Section 378, IPC), theft is taking someone's movable property without their consent, even if the owner is dead.

- So, Option 2: Theft is the right answer.

- Option 4, "None of the above," is incorrect because one of the options fits.
