  • A
    $-\frac{1}{3}$
  • B
    $-\frac{1}{3}$
  • $-\frac{1}{12}$
  • D
    $\frac{1}{12}$

Answer

Correct option: C.
$-\frac{1}{12}$

 Given that
we have to find the value of given expression
$​​​​\frac{1}{1+\frac{1}{3}}-\frac{1}{1+\frac{1}{2}}$
$=\frac{1}{\frac{1+3}{3}}-\frac{1}{\frac{1+2}{2}}$
$=\frac{3}{4}-\frac{2}{3} $
$=\frac{3\times3-2\times4}{12}$
$=\frac{1}{12}$
