Best answer
Correct choice is (c) Ethylmethylamine

Best explanation: When an amine is heated with CHCl3 and alc. KOH and does not give any reaction, it indicates that it is a secondary or tertiary amine. This is called as carbylamines test and the compound ‘X’ will be ethylmethylamine, as it is 2° and fails the test.
