a the desert southwest; winter
b the northeastern states; spring
c southern california; early summer
d western texas, oklahoma, and kansas; spring and early summer

Option (D)

Explanation:

The dry lines are the lines that split the dry air mass from the moist air mass. These lines generally move across a large continent and they are responsible for the occurrence of a severe type of weather pattern. These dry lines are most commonly found in the Aravalli ranges of Northern India and the eastern side of Rocky mountain in Northern America.

The presence of dry lines over an area results in a distinct drop in terms of humidity. They commonly develop over the western side of Texas, Oklahoma, and Kansas during the spring and early summer season.

Thus, the correct answer is option (D).
