Consider the table.

Types of Bacteria
\begin{tabular}{|c|c|c|}
\hline Form & Shape & Associated Disease \\
\hline Coccus & [tex]$X$[/tex] & Strep throat \\
\hline Bacillus & Rod shaped & [tex]$Y$[/tex] \\
\hline Spirillum & Spiral & Cholera \\
\hline
\end{tabular}

Which best describes [tex]$X$[/tex] and [tex]$Y$[/tex]?
A. [tex]$X=$[/tex] Spherical; [tex]$Y=$[/tex] E. coli
B. [tex]$X=$[/tex] Comma shaped; [tex]$Y=$[/tex] Whooping cough
C. [tex]$X=$[/tex] Oval shaped; [tex]$Y=$[/tex] S. aureus
D. [tex]$X=$[/tex] Rod shaped; [tex]$Y=$[/tex] Pneumonia

To determine the descriptions for [tex]\(X\)[/tex] and [tex]\(Y\)[/tex], let's review the characteristics and associated diseases of the given bacteria forms:

1. Coccus:
- Form: Coccus
- Shape: [tex]\(X\)[/tex]
- Associated disease: Strep throat

The term "Coccus" refers to bacteria that are typically spherical in shape. Therefore, [tex]\(X\)[/tex] is best described as spherical.

2. Bacillus:
- Form: Bacillus
- Shape: Rod shaped
- Associated disease: [tex]\(Y\)[/tex]

Bacillus refers to bacteria that are rod-shaped. Considering common bacterial diseases caused by rod-shaped bacteria, one such bacterium is Bacillus pertussis, which causes whooping cough. Thus, [tex]\(Y\)[/tex] is best described as whooping cough.

3. Spirillum:
- Form: Spirillum
- Shape: Spiral
- Associated disease: Cholera

So, comparing these descriptions with the given options:
- [tex]\(X =\)[/tex] Spherical; [tex]\(Y =\)[/tex] E. coli
- [tex]\(X =\)[/tex] Comma shaped; [tex]\(Y =\)[/tex] Whooping cough
- [tex]\(X =\)[/tex] Oval shaped; [tex]\(Y = \text{S. aureus}\)[/tex]
- [tex]\(X =\)[/tex] Rod shaped; [tex]\(Y = \)[/tex] Pneumonia

The best match is:
- [tex]\(X =\)[/tex] Spherical
- [tex]\(Y =\)[/tex] Whooping cough

So, the correct answer is:
[tex]\( X = \text{Spherical}; Y = \text{Whooping cough}\)[/tex]
