Explanation:

Moringa oleifera is a deciduous tree, occasionally growing up to 15 m in height. Almost all parts of the plant are potentially useful, including for food, fodder, medicine, fuel wood and fertiliser. The seeds are probably the most useful part of the plant, containing a significant percentage of high-quality oil. Recently, the large-scale cultivation of Moringa oleifera has been suggested as a potential source of biofuel. 

The exact origin of this species is somewhat obscure, M. oleifera is thought to be indigenous to the sub-Himalayan tracts of northern India. 

Hence, statement 1 is incorrect.

Tamarindus indica, commonly known as tamarind, is a frost-free, tropical evergreen tree belonging to family fabaceae, that typically grows to 40-60′ (less frequently to 90′) tall. It is native to eastern Africa, but is now commonly grown and in some cases has naturalised in a number of tropical to subtropical areas around the world. 

Hence, statement 2 is incorrect.

The tamarind seed oil has evolved as one of the most essential and economical biodiesel raw material oils.

India exports tamarind and seeds of moringa.
