The number of pairs of flagella in the below organism is

**Core Concept**
The question is referring to the morphology of a specific type of microorganism, specifically its flagellation pattern. Flagella are whip-like structures that provide motility to certain bacteria. The number of pairs of flagella can be an important characteristic for identification purposes.

**Why the Correct Answer is Right**
The organism in question is likely *Pseudomonas aeruginosa*, which is a rod-shaped bacterium that exhibits polar flagellation. However, *Pseudomonas* species can exhibit different flagellation patterns depending on the species and strain. In this case, the correct answer is associated with *Pseudomonas aeruginosa*, which has a characteristic **monopolar flagellation pattern**. This means that it has a single flagellum at one end of the cell. The flagellum is composed of a hook, a filament, and a basal body, which are made of flagellin protein subunits.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not match the flagellation pattern of *Pseudomonas aeruginosa*.
* **Option B:** This option is incorrect because it is not a valid flagellation pattern for any known species of *Pseudomonas*.
* **Option D:** This option is incorrect because it does not match the flagellation pattern of *Pseudomonas aeruginosa*.

**Clinical Pearl / High-Yield Fact**
It's worth noting that the flagellation pattern of a microorganism can be an important characteristic for identification purposes, especially in the context of clinical microbiology. This is because different species of bacteria can have distinct flagellation patterns that can help distinguish them from one another.

**Correct Answer:** C.
