Solution

The correct option is D
$\frac{3}{26}$

Since 26 is a multiple of 13, LCM of 13 and 26 is 26.

$1 - (\frac{8}{13} + \frac{7}{26})$ $= 1 - (\frac{8 \times 2}{13 \times 2} + \frac{7}{26}) = 1 - (\frac{16}{26} + \frac{7}{26}) = 1 - (\frac{16 + 7}{26}) = 1 - \frac{23}{26} = \frac{26 - 23}{26} = \frac{3}{26}$
