What is the arrangement in the basal body?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Basal Body**: The basal body is a structure that serves as the base for flagella and cilia in eukaryotic cells. It is crucial for the formation and anchoring of these organelles.

2. **Location of the Basal Body**: The basal body is located at the cell surface, specifically within a barrel-like structure. It is attached to the cell membrane.

3. **Arrangement of Microtubules**: The basal body has a specific arrangement of microtubules. It consists of a triplet arrangement of microtubules, which means that each set of microtubules is made up of three individual microtubules.
