Final answer:
In the summer, the name of Time Zones shift one hour later if the region observes Daylight Saving Time, changing the name to include 'Daylight', such as Pacific Daylight Time instead of Pacific Standard Time.
Step-by-step explanation:
What happens to the name of the Time Zones in the Summer depends on whether a region observes Daylight Saving Time (DST). When regions switch to DST, they effectively move the clock forward by one hour to extend evening daylight. Therefore, the correct answer to the student's question is:
c) They shift one hour later.
For example, in the case of Pacific Standard Time (PST), it becomes Pacific Daylight Time (PDT) during the summer months. Many time zones will add 'Daylight' to their name during this period, reflecting the shift forward by one hour. However, the standard time zone names, such as 'Eastern Standard Time' or 'Central Standard Time', return once Daylight Saving Time ends in the fall, when clocks are set back to standard time.
