What can cause excessive VSWR in RF cables used to connect a radio to an antenna?

D is the one. Excessive VSWR comes from an impedance mismatch between components, not antenna gain or radio output. Saw something like this in a practice set and the explanation was super clear for once!
Had something like this in a mock in the official study guide, thought it was A for a second.
Hard to say, some folks may pick A or C, but those just boost directionality, not VSWR. Pretty sure impedance mismatch (D) is the one that actually causes the issue here. Anyone see a different explanation?
