A. 49 hours

Explanation:

Unit:           1                          2                                           4                            8

Time:         10 hours           7 hours

Total Time:  10 hours        17 hours divided by 2

Average:    10 hours         8.5 (85% learning curve)    8.8 x .85 = 7.225   7.225 x .85 = 6.141

So total time taken by 8 rings will be 6.141 x 8 = 49.13 hours.
