Solution

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

$C H_{3} C O N H_{2} + B r_{2} + 4 N a O H ⟶ C H_{3} N H_{2} + N a_{2} C O_{3} + 2 N a B r + 2 H_{2} O$

The reaction occurs through intermediate formation of alkyl isocyanate which on hydrolysis gives methylamine and sodium carbonate.
