Answer 1

The correct option is C Place of origin of integuments

• The ridge formed by the fusion of funicle with the body of ovule is called Raphe.

• The space between integument and nucellus is called endostome.

• Integuments originate from the base of chalaza and terminate towards the micropyle where they cover the minute opening called micropyle.

• Place where the Nucellus communicates with the cavity of ovary is the Placenta.

Hence, chalaza is the place of origin of integuments.

So, the correct answer is C.
