Step 1: Frame the medico-legal scenario. This is a survivor of sexual assault who is a minor (16 years) and pregnant at 16 weeks, presumably seeking termination. Several statutory obligations apply.
Step 2: Apply the MTP Act (as amended 2021). For a pregnancy beyond 12 weeks and up to 20 weeks, termination requires the opinion of two registered medical practitioners, not one. Only up to 12 weeks does a single doctor's opinion suffice. At 16 weeks, two doctors' opinions are mandatory - so "MTP on one doctor's opinion" is the incorrect/NOT-included step.
Step 3: Validate the other steps. Under the POCSO Act, sexual assault of a minor is a mandatory reportable offence, so the police must be informed. The aborted fetal/products of conception should be preserved for DNA profiling as forensic evidence. As the patient is a minor, consent of the parent/guardian is required for the MTP procedure (the minor's own assent plus guardian consent).
Step 4: Select the answer. Since at 16 weeks two practitioners' opinions are needed, performing MTP on a single doctor's opinion is NOT part of correct management. Hence the answer is "MTP on one doctor's opinion."
