Answer:
The correct answer is A: Simple cuboidal epithelium.
Explanation:
Simple Cuboidal Epithelium: These epithelia are formed by a single layer of cuboidal cells, that are <em>as </em>tall as they are wide. They have a rounded, central nucleus. Occasionally these cells present cilia, flagella or <em>microvillus</em> in their apical surface, lining the lumen. Microvillus are fingerlike projections. This epithelium can be found for example in the proximal convolutes renal tubule.
