Final Answer :
C
Explanation :
Sieve tube elements are part of the phloem, not the xylem. The xylem is responsible for water and mineral transport in plants and contains tracheids, vessel elements, fibers, and parenchyma cells, but not sieve tube elements, which are involved in the transport of sugars and other nutrients in the phloem.
