Which of the following latitudes has the smallest variation in the length of day time during a year?

question 33 options:

55º n

15º s

65º n

45º s

Option (2)

Explanation:

The day and night occurs due to the rotation of the earth around its axis. The length of the day that one experiences depends upon the position of that person with respect to the latitude of the earth. This duration of day remains almost consistent in the equatorial region. Whereas, the variation in this length of day light changes with the increasing latitude. This means that at the equator, the variation in the duration of day is least and at the polar region, this variation is high. The duration of day in the equatorial region is nearly 12 hours throughout the year, whereas in the polar region this length changes from 0 to 24 hours.

Thus, according to the given condition, the 15° S is the region that is close to the equator. Here, there occurs least variation in the day length.

Hence, the correct answer is option (2).

d is the logical answer but im not a 100% sure
