Solution

The correct option is C Assertion is correct but Reason is incorrect
These containers usually have a plastic coating covering the entire inside.
The $A l_{2} O_{3}$ coatings WILL dissolve in concentrations of aqueous Nitric acid more dilute than about 90% $H N O_{3}$ .
$A l_{2} O_{3} (s) + 6 H N O_{3} (a q) \to 2 A l (N O_{3})_{3} (a q) + 3 H_{2} O$
Concentrations above 90% HNO3 are so strongly oxidizing that they do not react with the Aluminum oxide coating. Aluminum storage tanks for industrial sites have been used for storing $H N O_{3}$ , but Aluminum do not react with concentrated nitric acid since a thick, hard to dissolve oxidation layer builds (passive oxidation) that protects the metal against further assaults.
This Option C is correct.
