Text Solution

Verified by Experts

The correct Answer is:
A
Be is amphoteric as it reacts with acids and also with `NaOH` giving `H_(2)` ad sodium berrylate. Other Group 2 metals are purely basic as they do not react with NaoH
`Be+2NaOH+2H_(2)OtoNaBeO_(2).2H_(2)O+H_(2)`
or `Na_(2)[Be(OH)_(4)]` Sodium berrylate
