keywords: 

{'frequencies': [0, 0, 1, 1], 'frequency': [0, 0, 1, 3], 'diatonic scale': [0, 0, 1, 0], 'hz': [0, 0, 4, 8], 'musical scale': [0, 0, 1, 0]}

In Option 1, the statement is that a widely used musical scale, the diatonic scale, has seven frequencies. This is indeed correct; the diatonic scale is composed of seven distinct pitches or frequencies, making up the seven notes of the scale.

Option 2`s statement is that the frequency of the note `C` is 256 Hz and that of `C` an octave higher is 512 Hz. This is also accurate. In musical terms, an octave above a certain note is essentially a doubling of the frequency of that note. So, if a `C` note has a frequency of 256 Hz, a `C` note an octave higher will indeed have a frequency of 512 Hz.

Therefore, the answer is Option 3, as both statements given are correct.
