Question 1827Navigation General

The correct answer is D) 187°T. To obtain the best fix, the third bearing should be perpendicular to the first two bearings. The first two bearings of 313°T and 076°T form an angle of approximately 237°. The bearing that is perpendicular to this angle is 187°T, which is the correct answer. The other options are incorrect because they do not create the optimal 90-degree angle with the existing bearings. For example, 048°T and 101°T would create acute angles with the initial bearings, resulting in a less accurate fix.
