To determine the total number of hours Holly spent practicing the piano, we need to multiply the amount of time she practiced each session by the number of practice sessions.

Step-by-Step Solution:

1. Identify the amount of time Holly spent practicing in one session:
- Holly practiced for 0.6 hours each time.

2. Determine the number of practice sessions:
- Holly practiced 4 times.

3. Calculate the total hours spent by multiplying the time per session by the number of sessions:
- Total hours = (hours per practice session) (number of practice sessions)
- Total hours = 0.6 hours/session 4 sessions

4. Perform the multiplication:
- Total hours = 2.4 hours

Therefore, Holly spent a total of 2.4 hours practicing the piano, which corresponds to option C: 2.4.
