Hope it helps u dear :)

Answer 2

Diploid or 2n

Explanation:

The embryo sac contains seven cells but eight nuclei in its structure.  One nucleus from the chalazal end and one nucleus from antipodal end come in the large central cell and thus large cell contains two nuclei.

• These two polar nuclei present in the central cell fuse with each other before the process of fertilisation and a nucleus is formed known as secondary cells.
• The secondary nucleus since contains the two nuclei, therefore, is considered 2n or diploid structure. This diploid structure can fuse with the male nuclei and form a triploid structure called endosperm.
• Thus, diploid is the correct answer.
