A scientist is trying to determine how closely related a moth species (Species Z) is to four other moth species (Species A, B, C, and D). He examined the DNA of each species and compared it to Species Z. He then created this table.

| Species | # of Genetic Differences |
|----------|--------------------------|
| Species A| 12 |
| Species B| 3 |
| Species C| 14 |
| Species D| 28 |

Which species is most closely related to Species Z?

A. Species A
B. Species B
C. Species C
D. Species D

To determine which species is most closely related to the moth species (Species Z), we need to find the species that has the fewest genetic differences compared to Species Z.

Here is the given data in tabular form:

| Species | Number of Genetic Differences |
|-----------|-------------------------------|
| Species A | 12 |
| Species B | 3 |
| Species C | 14 |
| Species D | 28 |

We are looking for the species with the smallest number of genetic differences. Let's analyze each value:

- Species A has 12 genetic differences.
- Species B has 3 genetic differences.
- Species C has 14 genetic differences.
- Species D has 28 genetic differences.

Among these values, the smallest number is 3. Therefore, the species with the least number of genetic differences is Species B, which has only 3 genetic differences.

Thus, Species B is the species most closely related to the moth species (Species Z).
