Easy

A

A-Egg apparatus; B-Synergid; C-Polar nuclei; D-Male gametes; E-Vegetative Nucleus; F-Central cell
B

A-Obturator; B-Synergid; C-Polar nuclei; D-Male gametes; E-Vegetative Nucleus; F-Central cell
C

A-Filiform apparatus; B-Synergid; C-Polar nuclei; D-Vegetative Nucleus; E-Male gametes; F-Central cell
D

A-Filiform apparatus; B-Synergid; C-Polar nuclei; D-Male gametes; E-Vegetative Nucleus; F-Central cell

Solution
