Rusting of `Fe` is quicker in saline water than in ordinary water.

Answer

T

Explanation

The `Na^(o+)` and `Cl^(c-)` present in saline water increase the conductance of the solution in contact with the metal surface. This accelerates the formation of `Fe^(2+)` ions and hence that of rust, `Fe_(2)O_(3).Xh_(2)O`.
