Read the following statements
A)All the changes from pollen deposition on the stigma until the pollen tube enter the ovule are collectively called pollen pistil interactions.
B)Chemical dialogue between male gametes and antipodals is a prerequisite for post-pollination events.
C) Pollen tube enters into the ovule  from the micropylar end.
D)Pollen tube directly enters the egg cell to release male gametes.
Pick the correct statement.

The ability of the pistil to recognize the pollen followed by its acceptance or rejection is the result of a continuous dialogue between the pollen grain and the pistil. This dialogue is mediated by chemical components of the pollen interacting with those of the pistil.

Pollen tube, after reaching the ovary, enters the ovule through the micropyle and then enters one of the synergids through the filiform apparatus, but not the egg cell directly.
