To convert from Celsius to Fahrenheit, the formula used is:

\[ F = \frac{9}{5}C + 32 \]

In this instance, substituting -60 degrees Celsius into the formula gives:

\[

F = \frac{9}{5}(-60) + 32

\]

Calculating this step by step:

1. Multiply -60 by 9, which equals -540.

2. Divide -540 by 5, resulting in -108.

3. Finally, add 32 to -108, giving you -76.

Thus, -60 degrees Celsius translates to -76 degrees Fahrenheit. This process demonstrates the correct application of the conversion formula, leading to the answer that confirms a correct understanding of temperature conversion principles.

The other choices do not derive from the appropriate calculations; therefore, they do not represent the corresponding Fahrenheit value for -60 degrees Celsius.
