Answer 1

(3)

Explanation:

In the industrial preparation of ammonia by the Haber process, hydrogen may be obtained by the Bosch process. Therefore, the Assertion (A) is true.

The ratio stated in the Reason is incorrect. In the Haber process, nitrogen and hydrogen are taken in the ratio 1 : 3, not hydrogen and nitrogen in the ratio 1 : 3. Therefore, the Reason (R) is false.

Hence, A is true and R is false.
