B
2 or 4 seconds
C
4 to 6 seconds
D
8 to 10 seconds
AI Explanation
The correct answer is A) about 1 second. According to the navigation rules, both for international and inland waters, the duration of each blast of the whistle signals used in meeting and crossing situations is about 1 second. This is specified in the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules. The other options are incorrect because the rules do not specify blast durations of 2-4 seconds, 4-6 seconds, or 8-10 seconds for these types of whistle signals.
