Solution

The correct option is B STATEMENT-1 is True, STATEMENT-2 is True; STATEMENT-2 is NOT a correct explanation for STATEMENT-1
Both Dumas method and Kjeldahl's method are used for estimating Nitrogen.

Kjeldahl' method is not applicable to compounds containing N in nitro and azo groups and N present in the ring (pyridine) as N of these compounds does not change to $(N H_{4})_{2} S O_{4} .$

Dumas method is more applicable as it is faster than Kjeldahl's method. It gives immediate results. It is also easy to use.

Option B is correct.
