Which one is a taxon ?
(a) Order
(b) Family
(c) Genus
(d) All the above

Options

A. Order
B. Family
C. Genus
D. All the above

Answer

To determine which of the options is a taxon, let's analyze each option step by step.

### Step 1: Understand the term "taxon"
A taxon (plural: taxa) is a group of one or more populations of organisms that form a unit. It is a category used in the classification of organisms. Taxa are ranked in a hierarchical system, which helps in the organization and classification of living organisms.

### Step 2: Analyze the options
- **Option (a) Order**: This is a rank in the biological classification system. It groups together families that share certain characteristics. Therefore, "Order" is a taxon.

- **Option (b) Family**: This is also a rank in the classification system. It groups together genera that share certain characteristics. Thus, "Family" is a taxon as well.

- **Option (c) Genus**: This is a rank that groups together species that are closely related. Therefore, "Genus" is also a taxon.

- **Option (d) All the above**: Since all the previous options (Order, Family, and Genus) are taxa, this option suggests that all of them are correct.

### Step 3: Conclusion
Since all three options (Order, Family, and Genus) are indeed taxa, the correct answer is:
**(d) All the above.**
