B. Ethos and pathos
C. Logos and cosmos
D. Logos and pathos

The answer is A. Ethos and logos

Explanation:

In the excerpt, the section "Dr. William Leu, a board-certified cardiologist..." summarizes the experience and prestige of this doctor in the area of cardiology. This clearly demonstrates the use of ethos or the appeal to credibility. Indeed, these first details show the reader this Dr. is an expert in the area and his words must be believed. On the other hand, the use of statistics and details about the research of this Doctor is a way to use the logos appeal as this focuses on logic and evidence, which are also the base for medical research.
