Answer 1

The correct option is E Hard endocarp

Drupes are called as hard stony fruits because of the hard endocarp. A drupe or stone fruit is an indehiscent fruit in which an outer fleshy part-exocarp or skin and mesocarp or flesh surrounds a shell of hardened endocarp with a seed inside. These fruits usually develop from a single carpel and mostly from flowers with superior ovaries.
Thus, the correct answer is option E.
