To find the normal time (NT) for the task, we need to use the following formula:

NT = (OBSERVATIONS x ELEMENTS x RATING FACTOR) / TOTAL ALLOWANCE

- OBSERVATIONS: The number of times the task was observed (in this case, 5)
- ELEMENTS: The number of basic motions or actions required to complete the task (not stated in the problem)
- RATING FACTOR: The average rating factor based on the analyst's evaluation of the task (not stated in the problem)
- TOTAL ALLOWANCE: The total time for the task, including any allowances (not stated in the problem)

Since the problem does not provide values for ELEMENTS, RATING FACTOR, or TOTAL ALLOWANCE, we cannot calculate the exact NT for the task. However, we can use the given data to estimate the NT.

We know that the employee worked at a 25% faster pace than the average, so we can assume that their performance time is 25% less than the average time for the task. Therefore, the average time for the task is:

AVERAGE TIME = PERFORMANCE TIME / (1 + % IMPROVEMENT)
AVERAGE TIME = 96 / (1 + 0.25)
AVERAGE TIME = 96 / 1.25
AVERAGE TIME = 76.8 seconds

The NT for the task would then be:

NT = (OBSERVATIONS x ELEMENTS x RATING FACTOR) / TOTAL ALLOWANCE
NT = (5 x ELEMENTS x RATING FACTOR) / 76.8

Without additional information for ELEMENTS and RATING FACTOR, we cannot calculate the exact NT. However, we can determine the best choice from the given options.

Option C (100 seconds) is closest to our estimated average time of 76.8 seconds, adjusted for a 25% improvement in performance. Therefore, the best choice is C.
