Final answer:
The camera will reset 487 times in a year, and after the last reset, it will begin recording again and record for 18 hours into the next year before resetting again. Therefore, the correct answer is 18 hours.
Step-by-step explanation:
The question asks us to calculate how many hours a camera will record in a year before it resets if it resets every 18 hours. First, we find out how many times the camera will reset in a full year. There are 365 days in a year and 24 hours in a day, so there are 365 x 24 = 8760 hours in a year. If the camera resets every 18 hours, it will reset 8760 / 18 = 487 times in a year.
The camera records for 18 hours before each reset. Therefore, after the 487th reset, the camera will start recording again before reaching the full 8760 hours of the year. It will then record for 18 hours into the next year before resetting again. Thus, the correct answer to the question is A. 18 hours.
