B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C. If the assertion is true but the reason is false

Explanation

Circulation of biogenetic materials between the living and the non-living worlds is called cycles of matter of biogeochemical cycling. The important biogeochemical cycles that operates in bicosphere are carbon cycle, sulphur cycle, `O_(2)` cycle `N_(2)` cycle, etc. the whole of biogenetic nutrients are not alwyas in circulation . for example,rocks from which nutrients are very slowly transferred to the crycling pool.
