By which mechanism, the salt resistant plants can get rid off excess `Na^(+)` ions to the outer side, through the roots ?

Options

A. `H^(+)`-ATPase uniport system
B. `Na^(+)`- uniport system
C. `H^(+)- Cl^(-)` sympart system
D. `Na^(+)- H^(+)` antiport system

Answer

D

Explanation

The salt resistant plants get rid off excess `Na^(+)` ions to the outside throught the roots by `Na^(+)-H^(+)` antiport system.
