Select the correct statement.

Assertion : Deficiency of sulphur causes chlorosis in plants.

Reason : Sulphur is a constituent of chlorophyll, proteins and nucleic acids.

Assertion: As per carbonic acid exchange theory of mineral salt absorption, $\mathrm{CO}_2$ released during respiration of roots forms $\mathrm{H}_2 \mathrm{CO}_3$ when dissolved in soil water.

Reason: $\mathrm{H}_2 \mathrm{CO}_3$ dissociates into $\mathrm{H}^{+}$and $\mathrm{HCO}_3^{-}$ ions, where $\mathrm{H}^{+}$ions exchange with anions adsorbed on clay particles.
