Answer:
A) Intellectual property rights are strongly protected by U.S. patent laws.
Step-by-step explanation:
As when a patent is developed the most important thing is to get is registered so that no other company copies it and tries to gain advantage of the research and innovation.
In the given case the blender design is innovative, if the patent is not registered for the design the companies under competition might copy it.
And if the patent is not protected with a legal support through the intellectual property rights then the registered patent would also be copied, and the benefit of innovation would not be realized.
Accordingly, this is the strongest reason.
