• D. 1 and 2 both

Answer 1

The correct option is B Sieve tube element

Sieve elements are the major conducting cells in the phloem. Enucleated cells mean a cell without a nucleus. The sieve tube elements do not have nucleus hence they are considered enucleated. Sieve tube elements transport sugars over long distance through plants by acting as a channel.

So, the correct answer is 'Sieve tube element'.
