Solve the problem.The capsize screening value C is an indicator of a sailboat's suitability for extended offshore sailing. C is determined by the function C = 4D-1/3B, where D is the displacement of the boat in pounds and B is its beam (or width) in feet. The International Offshore Rules require that the capsize screening value be less than or equal to 2 for safety. What is the maximum allowable beam (to the nearest inch) for a boat with a displacement of 
A. 13 ft 8 in. B. 71 ft 3 in. C. 27 ft 3 in. D. 6 ft 10 in.
