Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Nitric acid is an oxidizing agent
$C u + 4 H N O_{3} \to C u {({N O}_{3})}_{2} + 2 {N O}_{2} + 2 H_{2} O$
$3 C u + 8 {H N O}_{3} \to 3 C u {({N O}_{3})}_{2} + 2 N O + 4 H_{2} O$
oxidizing agent $\to$ $C u$ gas reduced
$↓$
$C u$ has positive $E_{0}$
Both $A$ & $R$ are correct.
Reason is correct explaination.
