Differentiate between (i) mineral & ore (ii) matrix & flux.

(a). If both (A) and (R) are correct and (R) is the correct explanation for (A). (b). If both (A) and (R) are correct and (R) is not the correct explanation for (A). (c). If (A) is correct and (R) is incorrect. (d). If (A) is incorrect and (R) is correct. (e). If both (A) and (R) are incorrect. Q. Assertion (A): Dumas method is more applicable to nitrogen containing organic compounds than Kjeldahl's method. Reason (R): Kjeldahl's method does not give stisfactory results for compounds in which N is linked to O atom.
