Indian Economy - Understanding the basics of Indian economic system

Concerning the DANA (Depresión Aislada en Niveles Altos) phenomenon, consider the following statements

DANA is caused by a high-pressure system over the Mediterranean Sea leading to dry conditions.
The phenomenon involves the interaction between a pocket of cold air and warm, moist air over the sea.
Climate change has intensified DANA events, making them more severe and widespread.

Which of the statements given above are correct?

1&2 only

2&3 only

1&3 only

All of the above

Only statements 2&3 are correct.

DANA is not caused by a high-pressure system leading to dry conditions; rather, it is associated with low-pressure systems and atmospheric instability causing heavy rainfall.
DANA occurs when a pocket of cold air descends and interacts with warm, moist air over the Mediterranean Sea, leading to the formation of storm clouds and intense rainfall.
Climate change has led to warmer sea temperatures, increasing the amount of moisture in the air and intensifying DANA events, making them more severe and geographically widespread.

Hence option 2nd is correct.
