The correct answer is (d), all the above. Jatropha, Pongamia, and Aak are all petro plants.
A petro plant is a plant that can be used to produce biodiesel, a renewable fuel that can be used to power vehicles. Biodiesel is made from vegetable oils or animal fats, and it is a cleaner-burning fuel than petroleum diesel.
Jatropha is a shrub or small tree that is native to Central and South America. It is a fast-growing plant that can tolerate drought and poor soil conditions. Jatropha oil can be used to produce biodiesel, and the plant’s seeds can also be used to make soap and other products.
Pongamia is a tree that is native to India and Southeast Asia. It is a fast-growing plant that can tolerate drought and poor soil conditions. Pongamia oil can be used to produce biodiesel, and the tree’s wood can be used to make paper and other products.
Aak is a tree that is native to India and Southeast Asia. It is a fast-growing plant that can tolerate drought and poor soil conditions. Aak oil can be used to produce biodiesel, and the tree’s wood can be used to make paper and other products.
Petro plants are a valuable resource because they can be used to produce a renewable fuel that can help to reduce our reliance on petroleum.
