keywords: 

{'rainfall': [4, 1, 7, 3], 'cloud thunder': [0, 0, 0, 1], 'heavy downpour': [1, 0, 0, 3], 'lightning': [1, 0, 3, 6], 'daytime': [0, 0, 0, 1]}

The correct answer is option 1, which states that statements 1, 2, and 3 are correct. Let`s dissect each option to understand why this is the correct answer.

Statement 1: This statement correctly defines a cloudburst as a sudden and localized heavy downpour accompanied by cloud thunder and lightning. It describes the key characteristics of a cloudburst accurately.

Statement 2: This statement is also correct as cloudbursts mostly occur in hilly areas. The geographical features of hilly areas, such as steep slopes and narrow valleys, contribute to the formation of intense rain clouds that can result in cloudbursts.

Statement 3: This statement is correct as cloudbursts often result in a very high intensity of rainfall, typically ranging from 250 mm to 300 mm in just a couple of hours. This intensity of rainfall can lead to flash floods and other weather-related hazards.

Statement 4: This statement is incorrect. Cloudbursts can occur both during the daytime and nighttime. The timing of a cloudburst is not restricted to a specific period.

Overall, option 1 correctly identifies that statements 1, 2, and 3 are correct explanations of cloudburst
