Solution
A is true but R is false.
Explanation:
An unfertilized angiosperm embryo sac typically has seven cells and eight nuclei. Three antipodal cells, 2 synergids, 1 egg cell, and a central cell with 2 polar nuclei make up this structure. There are just 2 synergids and 1 egg cell in the egg apparatus. The polar nuclei are absent from it. The core cell, which is distinct from the egg machinery, contains the polar nuclei.
