The statement in option B is false because hard water can be supplied in lead pipes. The high mineral content in hard water (specifically calcium carbonate) forms an insoluble protective layer of scale on the inside of the pipes. This coating prevents the poisonous lead from dissolving and leaching into the water. It is soft water that can cause lead poisoning when supplied in lead pipes.

A. Helps animals to build strong teeth is a correct statement. The dissolved calcium in hard water contributes to strong teeth and bones in animals and humans.

C. Tastes better than soft water is generally considered a correct statement. The minerals present in hard water give it a distinct, often preferred, "full-bodied" or "mineral" taste compared to soft water.

D. Helps animals to build strong bones is a correct statement, for the same reason as option A. Hard water is a natural source of essential minerals like calcium, which are vital for maintaining bone density and overall skeletal health.

The correct answer is option B.
