Here's my breakdown of the answer. Mind you I spent four minutes on this question so it wasn't easy:
A- The prompt strictly discusses raising blood pressures affecting communication. It's true that medications lowering BP might fail when speaking, but in this option fluctuations can mean go up or down. So although this strengthens the claim that speaking causes changes in BP, this isn't the strongest support that it raises them.
B- This would be helpful only if we had a relative understanding of how much BP goes up for introverts and extroverts, but the text doesn't mention it. So this argument does not strengthen any point in the prompt.
C- The wording of this answer was meant to be confusing. It helps the argument that there is a positive increase in BP in introverts, but it is weak since it only relates to a specific subset of introverts, can't be easily generalized to all introverts, and is a stretch to assume sensing BP is accurate, let alone not the source of stress itself.
D- This most closely supports the idea that communication is stressful and causes a physical response in BP elevation, given signing (communication) causes stress.
E- There was no link discussing how extroverts and introverts differ in chronic BP increases, or needing to lower their BP. In fact the text suggest short term BP increases are lower in extroverts. If this was because they are taking medication to lower their BP, this would actually weaken the assertion that it's stress from communication that causes the rise in BP, since it's actually differences in medication that causes it.
I could easily eliminate E, but had to think very hard between A, C, & D.
C had difficult wording but once I got it could eliminate it, and A was weaker than D, especially because of the word "fluctuations" since it didn't specify raising BP.
