Explanation:

- Option 1: Who participates in the commission of crime with the charged accused

- This is correct. An accomplice actively takes part in the commission of the crime alongside the principal accused.

- Option 2: Who is a pretended confederate

- A pretended confederate is someone who only pretends to be part of the crime, often to trap others. They are not typically legally considered an accomplice.

- Option 3: Who is an informer

- An informer provides information to authorities, not participating in the crime itself, so they aren’t regarded as an accomplice.

- Option 4: All of the above

- Not correct, as only option 1 truly defines an accomplice.
