Solution

The correct option is C 260, 250
Beat frequency is given by
$\begin{matrix} f_{1} - f_{2} = 10 \\ (1) \end{matrix}$
Fundamental frequency $f \propto \frac{1}{l}$
$\begin{matrix} \frac{f_{1}}{f_{2}} = \frac{l_{2}}{l_{1}} = \frac{26}{25} \\ (2) \end{matrix}$
Solving equations 1 and 2 $f_{1} = 260 H z, f_{2} = 250 H z$
