Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Borax is the salt of a weak acid $(H_{3} {B O}_{3})$ and a strong base $(N a O H)$ .Borax forms alkaline aqueous solution.
$4 H_{3} B O_{3} + 2 N a O H \to N a_{2} B_{4} O_{7} + 7 H_{2} O$

Both Assertion and Reason are correct and Reason is the correct explanation for Assertio.
Hence option A is correct.
