The correct answer is option 3, which states that both statement 1 and statement 2 are correct.

Statement 1 is correct. The doldrums is a low pressure area located around the equator, where the prevailing winds are calm. This area is characterized by the absence or extremely weak winds. Sailors often used to get stuck in this region for days due to the lack of wind for their sails.

Statement 2 is also correct. Chinook is a type of warm, dry wind that occurs in winter. It blows down the eastern slopes of the Rocky Mountains in North America and can raise the temperature in a short amount of time. Chinook winds are known for their ability to rapidly melt snow and raise temperatures, providing relief from cold weather.

Therefore, both statements are correct, and option 3 is the correct answer.
