Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Option (A) is correct.
Beryllium carbonate is kept in the atmosphere of carbon dioxide as it is unstable and decomposes to give beryllium oxide and carbon dioxide.
$B e C O_{3} ⇌ B e O + C O_{2}$
When they are stored in the atmosphere of $C O_{2}$ , the concentration of $C O_{2}$ increases in the right side, making the reaction to shift towards backside so that the decomposition of beryllium carbonate is prevented.
