Answer 1

Right option is (b) Warning sound from the actual direction of a threat

The explanation: A stereo sound warning system is used to produce a warning signal with the direction of threat. It consists of speakers mounted all around the cockpit, if the threat is approaching from the left side, the speakers on the left side produce signals to warn the pilot.
