Consider the table:

Types of Bacteria

| Form | Shape | Associated Disease |
|----------|-------------|--------------------|
| Coccus | X | Strep throat |
| Bacillus | Rod shaped | Y |
| Spirillum| Spiral | Cholera |

Which best describes X and Y?

A. X = Spherical; Y = E. coli
B. X = Comma shaped; Y = Whooping cough
C. X = Oval shaped; Y = S. aureus
D. X = Rod shaped; Y = Pneumonia

Let's analyze the given information and the common knowledge about bacterial forms, shapes, and associated diseases:

1. Coccus: The term "coccus" refers to spherical-shaped bacteria. An example of a disease caused by coccus-shaped bacteria is strep throat, which is caused by Streptococcus bacteria.

2. Bacillus: Bacillus refers to rod-shaped bacteria. Diseases commonly associated with rod-shaped bacteria include infections caused by Escherichia coli (E. coli).

Given this information, we can match the shapes and associated diseases:

- [tex]$X$[/tex] should describe the shape of coccus bacteria, which is spherical.
- [tex]$Y$[/tex] should describe a disease associated with bacillus (rod-shaped) bacteria, an example of which is E. coli.

Thus, the best description for [tex]$X$[/tex] and [tex]$Y$[/tex] is:
- [tex]$X=$[/tex] Spherical
- [tex]$Y=$[/tex] E. coli

So the correct option is:
[tex]$X=$[/tex] Spherical; [tex]$Y=$[/tex] E. coli
