Correct answer: c) «B» of the International Code of Signals.
Why it is correct
Both Royal Decree 145/1989 and the International Code of Signals require any vessel loading, discharging or carrying dangerous goods to fly Flag 'B' (Bravo, red swallowtail) by day and show an all-round red light by night.

- b) Flag 'R' (Romeo) is not the dangerous goods signal.
- d) Flag 'N' (November) means 'No' (negative).
How to work it out in the exam
- Dangerous goods by day = Flag 'B' (Bravo); by night = all-round red light.
