Explanation:

Let’s explain each statement:

- 1. Abettor may be liable for a different offence than that for which principal is liable.

- This is *correct*. If the outcome of abetment is different than intended, abettor could face charges for a different offence.

- 2. Abettor is liable even if principal is innocent.

- *Correct*. Abettor can be punished independently if the act and intention constitute abetment, even if principal escapes liability.

- 3. Abettor’s liability is dependent on the liability of the principal.

- *Incorrect*. The liability of the abettor is independent and does not rely solely on conviction of the principal.

- 4. Abettor must have the same guilty intention or knowledge as the principal.

- *Incorrect*. The abettor must have the intent to aid or encourage the offence, but their mental state does not need to exactly match the principal’s.
