Solution
The correct option is A Martynia Martynia annua, commonly known as the tiger's claw. Pod green and fleshy at first, drying to a black woody capsule. Seeds brown to black, 2 to each pod. Often plants in the family are called "Devil's Claws" because of the 2-hooked form of their seed pods. The fruits are well adapted for dispersal by large mammals. Martynia annua (tiger’s claw), is provided with hook-like structures which are effective in their dispersal.
