उत्तर
Both Statements I and II are false.
Explanation:
Statement I is false because ordinary soap reacts with the calcium and magnesium minerals present in hard water to form an insoluble scum instead of producing a rich lather, which severely compromises its cleaning efficiency. Statement II is also false because a good laundry soap must be gentle on fabrics to prevent wear, tear, or discolouration, ensuring that delicate garments are not ruined while removing stains.
