Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
The three cells in the egg apparatus are arranged in triangular fashion as it enables the easy entry of male gametes through the chalazal end. A group of three cells in the seven celled embryo sac of an angiosperm consisting of the egg cell and two associated cells called synergids. The egg apparatus is located at the end of the embryo sac closer to the micropyle . The synergids are thought to direct the pollen nucleus to the egg cell as part of the process of double fertilization characteristic of angiosperms. The synergids degenerate after the egg cell has been fertilized.
