    C2, 3

    D1

    Answer:

    A. 1, 3

    Read Explanation:

    Flash floods are particularly dangerous due to their sudden onset and immense destructive power. Unlike general floods that may develop over hours or days, flash floods give little to no warning. They often occur in arid areas, mountainous regions, or urban settings where rapid runoff is prevalent. The swift flow of water in flash floods can carry away vehicles, structures, and even large debris, making them extremely hazardous. Warning systems and public awareness are crucial for minimizing casualties during such events.
