Final answer:
The question assumes an incorrect premise, as stink bugs cannot swim. Spheres are not inherently pointy, as they have a minimum surface area per unit volume and are more mobile due to reduced drag.
Step-by-step explanation:
The question assumes an incorrect premise. Stink bugs cannot swim, so the premise that stink bugs evolved to be able to swim is incorrect.
Spheres are not inherently pointy. In fact, spheres have a minimum surface area per unit volume and require the minimum amount of boundary. Spherical shapes are also more mobile due to their reduced drag.
Therefore, option B is the correct answer: Spheres are not inherently pointy; the question is based on a misconception.
