Solution
The correct option is B Albuminous cells
The analogous cells adjacent to the sieve cells of gymnosperms are called as albuminous cells. They are long, slender, conducting cells of the phloem. Sieve cells are found in gymnosperms. Albuminous cells are also called as Strasburger cells. They lack starch, thus making it possible to differentiate them from phloem parenchyma.
So, the correct answer is 'Albuminous cells'
