In which of the following both pairs have correct combination?

Options

A. `{:("Gaseous nutrient cycle","Carbon and nitrogen"),("Sedimentary nutrient cycle","Sulphur and phosphorus"):}`
B. `{:("Gaseous nutrient cycle","Carbon and nitrogen"),("Sedimentary nutrient cycle","Nitrogen and phosphorus"):}`
C. `{:("Gaseous nutrient cycle","Carbon and nitrogen"),("Sedimentary nutrient cycle","Carbon and phosphorus"):}`
D. `{:("Gaseous nutrient cycle","Carbon and nitrogen"),("Sedimentary nutrient cycle","Carbon and nitrogen"):}`

Answer

A

Explanation

The biogeochemical cycles are of two types, i.e. gaseous cycles, in which the reservoir for the nutrient elements is in the atmosphere (air )or hydrosphere (water). The four most abundant elements in the living systems, i.e. hydrogen. Carbon, oxygen and nitrogen have predominntly gaseous cycles.
