What does the Phragmoplast do?

Question

a) controls microtubule alignment at the cell plate.

b) Assists in deposition of plasmodesmata.

c) Is comprised of microfilaments controlling cell plate deposition.

d) controls lignin deposition at the cell plate.

It's either a or c... I think

Answer 1

c) Is comprised of microfilaments controlling cell plate deposition is correct:

"A phragmoplast is the central region of mitotic spindle of a plant cell at telophase, in which vesicles gather and fuse to form the cell plate, apparently guided by spindle microtubules."
