Saheli, a female antifertility pill is used

The correct option is A Weekly
Ormeloxifene (also known as centchroman) is one of the selective estrogen receptor modulators (SERMs), a class of medication which acts on the estrogen receptor. It is best known as a non-hormonal, non-steroidal oral contraceptive which is taken once per week. In India, ormeloxifene has been available as birth control since the early 1990s, and it is currently marketed under the trade name Saheli.

So, the correct answer is option B.
