Answer 2

c) establishing cell plate deposition is correct:

" In addition to phragmosome formation, preprophase is characterized by the formation of a ring of microtubules and actin filaments (called preprophase band) underneath the plasmamembrane around the equatorial plane of the future mitotic spindle and predicting (!!!) the position of cell plate fusion during telophase."

See chapter preprophase of this site:
