The Correct Option is A
Solution and Explanation
Evaluating the statements.
Xylem parenchyma indeed store substances like starch, but their walls are not typically highly thickened; that characteristic belongs to xylem fibers.
Companion cells are indeed associated with sieve tubes but are not controlled by them; they assist in the function of sieve tubes.
Phloem parenchyma is indeed scarce in most monocots.
Companion cells are indeed associated with sieve tubes but are not controlled by them; they assist in the function of sieve tubes.
Phloem parenchyma is indeed scarce in most monocots.
