    Bഒന്നും മൂന്നും

    Cരണ്ട് മാത്രം

    Dഇവയൊന്നുമല്ല

    Answer:

    C. രണ്ട് മാത്രം

    Read Explanation:

    • A drought is not merely a lack of rain, but rather a prolonged period where rainfall is significantly below the average expected for a specific region and time of year. This 'deficiency' is crucial as what might be considered normal rainfall in one arid region could be a severe drought in a humid one. This statistical deviation from the norm helps quantify and classify the severity of a drought.
