Answer 1

1 st one is correct

Explanation:

First, let's go through formation of the diazonium salt, a process called “diazotization”. The first key reagent for this process is either sodium nitrite (NaNO2) or nitrous acid (HNO2). Sodium nitrite has the advantage of being an easily handled salt, while HNO2 is a somewhat unstable liquid.
