• C. Sansevieria
• D. Pepromia

Answer 1

The correct option is D Pepromia

Peperomia is a small perennial epiphyte growing on rotten wood. These plants are naturally propagated by seeds but these are commercially propagated by leaf or stem cuttings. The petiole is an important part of leaf which is used for the propagation. Leaves are harvested from stock plants for which propagation is desired. The petiole section of each leaf is sterilized and cultured on a nutrient media which forms callus and finally develops into a plantlet.

So, the correct answer is option D.
