The length of the day changes from place to place and from season to season. The table below shows the times of sunrise and sunset on a certain day in August in certain cities of the world. Latitude is the angular distance of a place north or south of the earth's equator, usually expressed in degrees and minutes. The table also shows the latitudinal positions of these cities.

Table 2.1

City Sunrise time (in hours) Sunset time (in hours) Latitude
Tokyo 4:50 18:45 35$^\circ $ 41' N
New Delhi 5:53 18:55 28$^\circ $ 36' N
Johannesburg 6:45 17:40 26$^\circ $ 12' N
London 5:30 20:45 51$^\circ $ 30' N
New York 5:55 19:59 40$^\circ $ 42' N
Los Angeles 6:05 19:50 34$^\circ $ 3' N
Adelaide 6:45 17:55 34$^\circ $ 56' N

Figure 2.1

Based on the figure and the table, which of these is the MOST accurate conclusion?

A

The length of the day is more as we move away from the equator.

B

The longest days of all the places are equal but the time of sunrise and the time of sunset varies.

C

Places in the northern hemisphere have a longer day than those is the southern hemisphere.

D

The variation in the length of the day during the year is more as we move away from the equator.
