To calculate the standard time, we need to use the following formula:

Standard time = Average observed time × Performance rating factor × Allowance factor

We can find the average observed time by summing up all the cumulative times for each element and dividing by the number of cycles:

Average observed time = (41.2 + 16.5 + 19.7 + 23.6) / 20 = 25.25 seconds

Next, we can find the overall performance rating factor by multiplying the performance rating factors for each element:

Overall performance rating factor = 1.00 × 0.80 × 0.90 × 0.90 = 0.648

Finally, we can plug in our values for the allowance factor and the performance rating factor to find the standard time:

Standard time = 25.25 seconds × 0.648 × 1.20 = 19.65 seconds

Converting seconds to minutes, we get:

Standard time = 19.65/60 = 0.3275 minutes

Rounding to two decimal places, we get:

Standard time = 0.33 minutes or 12.10 seconds (rounded to the nearest second)

Therefore, the best choice is B.
