Explanation:

- Option 1: Deceiving somebody

This refers to misleading or tricking someone, often to gain advantage. It doesn't relate to "daggers drawn."

- Option 2: Without hope

This means being in a situation where nothing can be done to improve things. It is unrelated to conflict or hostility.

- Option 3: Friendly with each other

This describes a positive, amicable relationship. It’s the opposite of hostility, which is implied by the idiom.

- Option 4: Bitterly hostile

"At daggers drawn" means being in a state of open hostility or conflict, ready for confrontation. So, this fits perfectly as the meaning.
