Which of the following part of carrot contains the highest carotene level ?
Show Hint
In carrot roots, carotene is concentrated in the outer phloem tissue (cortex) and increases toward the distal end (tip) of the root.

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Carrot (Daucus carota) is a source of $\beta$-carotene, a precursor of Vitamin A.
The distribution of carotene is not uniform throughout the root tissue and varies across different anatomical regions.
Step 2: Detailed Explanation:
Anatomically, a carrot root is divided into two primary parts: the outer phloem (cortex) and the inner xylem (core).
The phloem (outer part) contains higher concentrations of sugars and carotenoids compared to the xylem (inner core).
Spatially, the concentration of carotene also varies along the length of the root.
The concentration of $\beta$-carotene is lower at the top (crown) and increases toward the tip or distal end of the root.
The distal end of the root contains the highest concentration of carotene because it matures later and accumulates pigments as the root elongates.
Selecting carrots with small cores and deep orange color at the tip indicates higher carotene content.
Step 3: Final Answer:
The part of the carrot containing the highest carotene level is the distal end of the root, which corresponds to Option (C).
