S3: Relying on traditional home remedies or advice from unqualified individuals for suspected STI symptoms ensures effective and timely treatment.

Correct answer: C S3 and S4 only

Let's evaluate each statement to identify the NOT effective or harmful practices: S1: NCERT explicitly states that avoiding sex with unknown partners/multiple partners is a simple principle to prevent STIs. This is an effective measure. S2: NCERT mentions that the use of condoms has an additional benefit of protecting the user from contracting STIs and AIDS. This is an effective measure. S3: Consulting unqualified individuals ('quacks' as mentioned in the context of MTP, implying general medical care) for suspected STIs is harmful as it delays proper diagnosis and treatment by qualified medical professionals. This is NOT an effective practice and is harmful. S4: Ignoring symptoms, even if mild, can lead to severe complications later. Early detection and treatment are crucial. This is NOT an effective practice and is harmful. S5: Creating awareness about STDs and related aspects is a major task under RCH programmes to build a reproductively healthy society. This is an effective measure. Therefore, statements S3 and S4 describe practices that are NOT effective or are harmful. This question tests the understanding of proper preventive and management strategies for STIs, differentiating them from ineffective or detrimental approaches.
