Concept: Under Hire Purchase, possession passes immediately, but ownership transfers only after all installments are fully paid.
Explanation:In a hire purchase agreement, the buyer receives the goods and makes installment payments over time.
However, the seller retains legal ownership until the buyer completes the payment schedule.
Only when the final installment is paid does the seller transfer full legal ownership to the buyer.
Thus, completion of all agreed installments is the point at which ownership changes hands.
Answer: D. the final instalment is paid.
