Assertion : Coconut tree is distributed in coastal areas over a large part of the world. Reason : Coconut fruit can float and get dispersed over thousands of kilometers before losing viability.

Step-by-step solution

Coconut requires the hot and wet climate hence it is grown in coastal areas. It is widely grown in coastal and deltic regions of tropical and subtropical countries. Coconut fruit shows hydrochory i.e. the dispersal takes place through water medium. Being the inhabitant of coastal area the fruit is so adapted that it can float and get dispersed over thousands of kilometers before losing viability.
