Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Kjeldahl's method is a faster method than Dumas' method. However, this method is used only for those organic compounds that are converted quantitatively to ammonium sulphate on heating strongly with concentrated sulphuric acid.
It involves $C u S O_{4}$ or Hg as a catalyst.
Kjeldahl's method cannot be used for the organic compounds,
Containing nitrogen in the ring, e.g., pyridine, quinoline etc.
Containing nitro ( $- N O_{2}$ ) and diazo (-N = N-) groups.

Whereas duma's method can be applied to the for the nitrous compound

Hence, the correct option is $B$
