• C. Tegmen
• D. Nucellus

Answer 1

The correct option is A Endosperm

Xenia in plants is the effect of pollen on seeds and fruit. The term was coined in 1881 by Wilhelm Olbers Focke to refer to effects on maternal tissues, including seed coat and pericarp, but at that time endosperm was also thought to be a maternal tissue, and the term became closely associated with endosperm effects. The term metaxenia was later coined and is still sometimes used to describe the effects on purely maternal tissues.
