First, we need to calculate the average cycle time for the worker:
Cycle 1: 54.78 seconds
Cycle 2: 57.81 seconds
Cycle 3: 54.67 seconds
Cycle 4: 53.47 seconds

Average cycle time = (54.78 + 57.81 + 54.67 + 53.47) / 4 = 55.43 seconds

Next, we need to apply the performance rating factor and allowance factor:

Corrected time for Element 4 = (53.47 x 1.10) x 1.20 = 71.77 seconds

Therefore, the standard time for Element 4 is 71.77 / 4 = 17.94 seconds.

Round to two decimal places, the answer is B) 56.23 seconds.
