The northern hemisphere is warmer in spring than in winter, because in spring
a) the days are shorter.
b) it gets more direct sunlight.
c) the earth is closer to the sun.
d) it is tilted away from the sun.

Option (B)

Explanation:

When the tilt of the earth is towards the sun, then it is called summer in the northern hemisphere. In this position, the sunlight is directly over the earth, as a result of which it absorbs more amount of heat. Spring is the season that starts from about 21st March to 21st of June or it can be considered as the season that exists between the summer and winter. Here, a high amount of sunlight is absorbed due to which the temperature eventually rises.

This is the reason why the northern hemisphere is relatively warmer during the spring season than in winter.

Hence, the correct answer is option (B).
