South-west Asia, Central Asia, Siberia are the areas of ________.

The correct option is B low rainfall
South-west Asia, Central Asia, Siberia are the areas of Low rainfall.

Most of eastern China, North Ko­rea, South Korea, and Japan are included in this region which lies entirely north of the Tropic of Cancer. Summers get rain­fall, and winters are dry—a definite monsoonal trait. Only Taiwan, and south­ern islands of Japan including southern half of Honshu, receive rainfall in winter caused by the southeasterly winds which bring rainfall after picking up moisture on the Japan Sea, East China Sea, and the ad­joining seas. The range of temperature increases in the interiors, as the winters be­come colder and summers warmer.
