Best answer
Answer: 1. blocks estrogen receptors in the uterus, preventing eggs from getting implanted.
Key idea: Saheli is a non-steroidal oral contraceptive pill developed in India (CDRI, Lucknow).
It is taken once a week. It acts as a selective estrogen receptor modulator: it blocks estrogen receptors in the uterus, so implantation fails. It is not an IUD, does not raise estrogen and is not a post-coital pill.
Answer: option 1.
