Understanding the Answer

Let's break down why this is correct

Answer

The first step is collecting samples from the human body (D), because you need material to study. Next, you sequence the microbial DNA (B) to identify which bacteria are present. After sequencing, you characterize the healthy microbiome (A) by cataloging the species and their typical functions. Finally, you analyze the relationship between the microbiome and health (C) to see how changes affect disease or wellness. This sequence moves from raw data to practical health insights.

Detailed Explanation

First we collect samples from the body to see what microbes are present. Other options are incorrect because Sequencing cannot happen before samples are taken, so starting with sequencing is impossible; Sequencing before collecting samples is like trying to bake a cake without ingredients.
