Solution

The correct option is C Sieve tubes
Sieve tubes have tubular cells with perforated walls and are living in nature. In-plant anatomy, sieve tube elements, also called sieve-tube members, are a specialized type of elongated cell in the phloem tissue of flowering plants. The ends of these cells are connected with other sieve-tube members, and together they constitute the sieve tube.
Therefore, the correct answer is option C.
