The correct option is C.

Explanation: ppm is used to measure the concentration of solute in a given volume of solution. ppm is basically parts per million.

Mathematically,

$ppm=\frac{\text{Mass of solute (in mg)}}{\text{Volume of solution (in L)}}$

We are given:

Mass of methanol = $1.56\times 10^{-5}g=1.56\times 10^{-2}mg$ (Conversion Factor : 1g = 1000mg)

Volume of solution = 250 mL = 0.250L (Conversion Factor : 1L = 1000mL)

Putting values in above equation, we get:

$ppm=\frac{1.56\times 10^{-2}mg}{0.250L}$

Concentration of methanol = 0.062ppm

Hence, the correct option is C.
