Solution
The correct option is BMartynia
Fruits and seeds of many plants are provided with hooks, spines, barbs or stiff hairs (Fig. 469) so that if an animal grazes or brushes against them, these stick to the animal’s body or clothing.
Later on, these drop off somehow or other and are thereby dispersed. Thus, the fruits of Xanthium strumarium (cocklebur), Urena lobata, Martynia annua (tiger’s claw), etc., are provided with hook-like structures which are effective in their dispersal.
