Option D is correct. While the general rule under Section 136 is that leading questions cannot be asked in examination-in-chief (your own witness), Section 137 provides exceptions: (1) with court permission on introductory matters; (2) if the court is satisfied the matter has already been sufficiently proved. Both exceptions in options A and B are recognized by law. Therefore 'Both (1) and (2)' is correct - leading questions may be asked in examination-in-chief in either of these circumstances.
