    Criteria for declaring the withdrawal of monsoon:
    - Cessation of rainfall activity: One of the criteria used by IMD for declaring the withdrawal of monsoon from extreme north-western parts of India is the cessation of rainfall activity over the area for continuous 5 days. This indicates a significant reduction in the monsoon rainfall, signaling the withdrawal phase.
    - Considerable reduction in moisture content: Another operational criterion is the considerable reduction in moisture content in the region. This reduction in moisture levels is a key indicator that the monsoon is withdrawing from the area.

    Explanation of the correct answer:
    The correct answer is option 'B' because both the criteria of cessation of rainfall activity and considerable reduction in moisture content are used by IMD for declaring the withdrawal of monsoon from extreme north-western parts of India. The establishment of a cyclone in the lower troposphere is not a specific criterion mentioned by IMD for this purpose. Therefore, options 1 and 3 only (cessation of rainfall activity and reduction in moisture content) are the correct criteria for declaring the withdrawal of monsoon in this region.
