Answer

Brief Explanations:

Interpolation is used for values within the data - set range, and extrapolation for values outside. The data - set has number of keys above middle C values of 0, 1, 2, 4, 8. Since 12 is greater than 8, it is outside the data - set. So, it is extrapolation.

Answer:

extrapolation, because a key that is 12 keys from middle C is outside the data set
