The correct option is B: Increased intensity of the murmur with deep inspiration

Explanation:

Most times, systolic heart murmurs do not mean that the individual might be suffering from a cardiac disease, it is simply connected to physiologic increases in the velocity of blood flow.

With deep inspiration, such murmurs, especially that of insufficiency of the tricuspid, increases in intensity.
