The correct option is A polar region
The sun begins to shine
in the tundra (Polar region) around
February-March. In the
beginning, the sun shines
for a maximum of an hour
and a half and then sets.
Gradually, it lengthens to 2
hours, 6 hours, 8 hours, 16
hours, and finally 24 hours!
Then for almost three
months from May to July,
the sun never sets, it shines
all 24 hours.
