Question 30Navigation General

The correct answer is B) B. In the U.S. Aids to Navigation System on the Western Rivers, the light characteristic of group flashing (2) is B. This is based on the U.S. Coast Guard regulations for the U.S. Aids to Navigation System, which specify that group flashing lights have a light pattern where two flashes are followed by a longer eclipse period. The other options are incorrect because A) A is for a single-flashing light, C) C is for a quick-flashing light, and D) D is for a very quick-flashing light, none of which match the group flashing (2) characteristic.
