Step 1: The legal hook for exhibitionism is its nature as a public obscene act, not the perversion itself.
Step 2: Indian law penalises obscene acts committed in or near a public place under Section 294 IPC, which covers exactly this exposure-for-gratification scenario.
Step 3: The penalty laid down is up to three months imprisonment or fine, confirming Section 294 as the answer.
Step 4: The distractors map to unrelated offences - public nuisance and counterfeiting provisions - so none of them governs exhibitionism.
