Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Students often generalize the mechanism of 'oral contraceptive pills' (inhibiting ovulation via negative feedback) to all pills.
The trap is failing to distinguish between the systemic steroidal mechanism of standard pills and the localized, receptor-modulating (non-ovulation-suppressing) mechanism of the non-steroidal pill 'Saheli'.
