Hint:

Remember bacterial shapes: Cocci = Spherical Bacilli = Rod shaped Vibrio = Comma shaped Spirilla = Spiral shaped

Answer 1

The Correct Option is A

Concept: Bacteria are classified on the basis of shape. Morphological classification is one of the simplest methods of bacterial categorization. Different bacterial shapes have specific scientific names. The major bacterial forms include spherical bacteria, rod-shaped bacteria, comma-shaped bacteria and spiral-shaped bacteria. Understanding these shapes helps us correctly match the terms.

Step 1: Identify spherical bacteria.
Spherical bacteria are known as cocci. They are round or globe-shaped bacterial cells. Examples include Streptococcus and Staphylococcus. Therefore \[ A\rightarrow II \]

Step 2: Identify rod-shaped bacteria.
Rod-shaped bacteria are scientifically called bacilli. These elongated bacterial cells include organisms such as Lactobacillus. Thus \[ B\rightarrow IV \]

Step 3: Identify comma-shaped bacteria.
Comma-shaped bacteria are known as vibrio. A well-known example is Vibrio cholerae which causes cholera. Hence \[ C\rightarrow I \]

Step 4: Identify spiral-shaped bacteria.
Spiral bacteria are called spirilla. These organisms possess twisted spiral structure. Therefore \[ D\rightarrow III \] Final matching becomes \[ A-II,\;B-IV,\;C-I,\;D-III \] Thus answer is \[ \boxed{\text{Option (1)}} \]
