Explanation:

Here’s the thing—good faith in the Indian Penal Code (IPC) doesn’t just mean doing something “honestly.” Let’s break down each option:

- Option 1: Honestly

• Doing something honestly is important, but by itself, it’s too narrow. You might be honest but still careless.

- Option 2: In Bona-fide manner

• "Bona fide" means good faith, but again, the IPC gives a more specific standard.

- Option 3: With due care and attention

• This is the correct answer. Section 52 of IPC defines “good faith” as doing something with due care and attention. Honesty alone isn’t enough—you actually have to be careful.

- Option 4: Without fault

• This isn’t accurate; people can act in good faith and still make mistakes. Not every error is due to "fault."
