As sieve tubes (a) posses broader lumen and perforated cross walls it is better suited for translocation.
Explanation:
- The phenomenon through which the food prepared through photosynthesis in leaves is transferred to other parts of the plant is called translocation.
- We know that xylem conducts the movement of water whereas phloem conducts the movement of food material.
- Phloem is composed of long tube-like cells that are devoid of the nucleus called sieve tubes.
- Sieve tubes have boarded lumen and perforated cross walls through which the movement of food occurs without any hindrance.
- Thus option (a) is considered as the best answer for the given question
