The correct answer is option 4. The National Green Tribunal deals with cases related to environmental protection and conservation of forests. This means that it handles legal matters pertaining to the preservation and safeguarding of the environment and forests.

Option 1, issues relating to protection and conservation of historical monuments, is incorrect as this falls under the purview of different authorities such as the Archaeological Survey of India.

Option 2, civil cases, is also incorrect as the National Green Tribunal specifically focuses on environmental issues and not general civil cases.

Option 3, criminal offences, is incorrect as the National Green Tribunal primarily deals with environmental cases and not criminal offenses.

Therefore, option 4 is the correct answer as it accurately reflects the jurisdiction of the National Green Tribunal in relation to environmental protection and conservation of forests.
