Answer: C. 70

A driver on Cycle 1 must not drive after completing 70 hours of on-duty time in seven consecutive days.

Why this is the answer

The handbook's hours-of-service section lists two cycles and gives each one a maximum. For Cycle 1, it says a driver stops driving once 70 on-duty hours are completed within seven days. That is the limit the question asks about. The passage does not tie this number to 14 days or to U.S. rules; those are separate limits described elsewhere. So the seven-day cap for Cycle 1 is the supported answer.

Why the other answers are wrong

Remember it

Remember Cycle 1 as the seven-day, 70-hour cycle.
