Answer:

The correct answer will be- true, all the options are correct.

Explanation:

Cactus or the species of Opuntia genus are adapted to grow on the desert conditions or the area with no water or xerophytic conditions.

The leaves of the plants become modified to take the shape of the spines which provide many advantages like protection from herbivores and providing shape to the plant.

In the species of teddy bear cactus <em>(Opuntia bigelovii)</em>, the cactus serve a third purpose that is they help in the propagation of the species. The spines possess tiny barbs at the ends which help them attach to the animal or any object that walks by and the falls of somewhere else. The fall-off portion of the cactus grow roots and form a new cactus there.

Thus, true is the correct answer.
