It took 80 hours of analysis to complete the first phase,but the second phase was done in 74 hours.If this learning rate continues,then the 8^th analysis should take a mere: A)63 hours and 20 minutes,give or take. B)68 hours and 30 minutes,give or take. C)57 hours and 15 minutes,give or take. D)52 hours and 45 minutes,give or take.

The learning rate is calculated as the difference in time between the first and second phases, which is 6 hours (80 - 74). Assuming a constant learning rate, each subsequent phase should take 6 hours less than the previous one. By the 8th analysis, the time should be reduced by 7 intervals of 6 hours (42 hours), resulting in 80 - 42 = 38 hours. However, the options provided do not match this calculation, so the closest approximation based on the pattern is option A.
