We can use the formula: frequency = speed of light / wavelength.

First, we need to convert the wavelength from nm to meters:

300 nm = 300 × 10^(-9) m = 3 × 10^(-7) m

Then, we can substitute the values into the formula:

frequency = (2.69 × 10^18 m/s) / (3 × 10^(-7) m) 
frequency = 8.97 × 10^14 Hz

Therefore, the frequency of the wave in the medium is 8.97E+14 Hz. The correct choice is C.
