If N and S both are present in an organic compound during Lassaigne’s test, both will change into

Na + S + C + N → NaSCN(A) is not correct because S and N will react with Nametal to form NaSCN simultaneously.(C) is not correct because Na2SO3 cannot be formed(D) is not correct because NaCNO is not formed.Hence, the correct answer is (2).
