Solution

The correct option is A Sucrose
Sieve tissues are a bunch of specialized types of elongated cells in the phloem tissue of flowering plants that transport carbohydrates, primarily sucrose, in the plant (e.g., from the leaves to the fruits and roots). Unlike the water-conducting xylem that is dead when mature, sieve elements are living cells. They are unique in lacking a nucleus at maturity.
