Question

Assertion : Pure `N_(2)` is formed from `Ba(N_(3))_(2)`
Reason : Thermal decomposition of `NaN_(3)` is used to inflate the air bags used for safety devices in same cases.
A. If both assertion and reason are correct and reason is correct explanation for assertion.
B. If both assertion and reason are correct but reason is not correct explanation for assertion.
C. If assertion is correct but reason is incorrect.
