D.
Detailed Explanation
Choice A is correct. Choice A is the correct answer. Evaluate the objective function at the vertices of the feasible region. 1. Vertices: , , . 2. Evaluate at (0,0): 3. Evaluate at (5,0): 4. Evaluate at (0,5): 5. Maximum: The largest value is 15. Strategic Tip: The maximum/minimum in linear programming always occurs at a vertex (corner point). Choice B is incorrect because 10 is not the maximum. Choice C is incorrect because no vertex yields 12. Choice D is incorrect because no vertex yields 13.
Key Steps:
