AI Explanation

The correct answer is C) 83322. To encode group Nddff, we need to follow the rules for the Voluntary Observing Ship Program and the WS Form B-80. For the given information: - The apparent wind is from 144° relative at 8 knots. - The vessel is on course 162°T at 15 knots. The correct encoding for Nddff is 83322, where: - N = 8 (wind direction from 144° relative) - dd = 33 (wind direction 144°) - ff = 22 (wind speed 8 knots) The other options are incorrect because they do not properly encode the given wind direction and speed information.
