The Act extends to:

The territorial extent defines the geographical area over which a law has jurisdiction. For provincial legislation, its scope is typically limited to that province. Whole of the Punjab correctly identifies that the Act applies uniformly across the entire province.

• Whole of the Punjab is correct, indicating the Act's comprehensive application throughout the province.
• Lahore Division only is too restrictive, as the Act's authority is not confined to a single division.
• Whole of Pakistan is incorrect because a provincial act does not extend to the entire country, which falls under federal jurisdiction.
• Selected districts is also false, as it implies partial application rather than full provincial coverage.
