The correct option is A (ii) and (iv)
Date palm
Date palm trees bear dates which are superior berries developed from monocarpellary, unilocular superior ovaries. The fruit wall or pericarp consists of membranous epicarp and endocarp and a fleshy mesocarp. The entire pericarp is edible and only the seeds are the non-edible parts.
Plum
Plum is a drupe. Drupes are stone fruits as they have a hard and stony endocarp. The endocarp usually encloses one seed. Drupes develop from mono or multicarpellary, superior or inferior ovaries, e.g, mango, coconut, etc. In superior drupes, the epicarp forms the outer skin. In plum, both the epicarp and the fleshy mesocarp are edible.
