Attempt or abetment penalty:

This question addresses the principles of criminal liability concerning attempts and abetment of offenses.

Option B: Same as main offence is the correct answer. Many penal codes and specific regulatory acts, including those in Pakistan, prescribe the same punishment for attempting or abetting an offense as for committing the offense itself. This reflects a legislative intent to deter preparatory acts and complicity by equating the criminal intent and actions leading to an offense with the completed act.

• Option A: Lesser than main offence is often true in some contexts but not universally, especially when the law explicitly equates the penalties.
• Option C: Only fine and Option D: Only warning are incorrect, as most serious offenses carry imprisonment, and attempts/abetments would typically carry the same range of penalties.
