Explanation

Chhaya & Saheli are brand names for a unique oral contraceptive pill available under India's national family planning program.
They contain the active ingredient Centchroman (also known as Ormeloxifene), which is a non-steroidal, non-hormonal compound.
Unlike traditional birth control pills that prevent ovulation using hormones, Chhaya works by altering the uterine lining to prevent a fertilized egg from implanting.
This makes it a suitable option for women who cannot or do not wish to use hormonal contraceptives.

Option A: Combined Oral Contraceptives (COCs) are, by definition, hormonal. They contain a combination of two synthetic steroid hormones: estrogen and progestin.
Option B: Progestin-Only Pills (POPs) are also hormonal. They contain a synthetic version of the steroid hormone progestin.
Option D: Levonorgestrel is a synthetic progestin, which is a steroid hormone. This pill is a high-dose hormonal contraceptive used for emergency purposes, not regular use.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification of oral contraceptives, specifically non-hormonal options available in India as background academic context rather than a clinical decision trigger.
Nurses must be aware of non-hormonal options like Chhaya for women who have contraindications to hormonal contraceptives, such as a history of thromboembolic disorders, estrogen-dependent tumors, or severe liver disease.
This option is particularly relevant in the Indian public health system where it is promoted as a safe, effective, and locally developed contraceptive.
Patient counseling is crucial. Nurses should explain the unique weekly dosing schedule of Chhaya and emphasize that it does not protect against sexually transmitted infections (STIs).

How to Approach the Question

First, identify the key defining terms in the question: 'non-hormonal' and 'non-steroidal'. This is the primary filter for the correct answer.
Second, analyze each option based on your knowledge of pharmacology and family planning methods.
Recall that 'Combined Oral Contraceptives' and 'Progestin-Only Pills' are named for the hormones they contain (estrogen and progestin), which are steroids. This eliminates options A and B.
Recognize that Levonorgestrel is a type of progestin, making the emergency contraceptive pill a hormonal, steroidal option. This eliminates option D.
By elimination, 'Chhaya & Saheli' is the only remaining option. Your knowledge of contraceptives available in India would confirm that these are brand names for the non-hormonal drug Centchroman.
