About prepositions and their usage:

• Prepositions are words that relate the position of noun with the rest of the sentence. They tell about the posture of it.
• Some of the prepositions include: on, in, to, up, down, behind, near, over, beside, beneath, etc.,
• Sometimes two prepositions may be combined to form a new preposition and they may provide a new meaning as well. Some of which are: into, upto, upon, etc.,
• Here they have given a person's address. So it means we have to give the detail of where he lives.
• 'On' is used when we want to say something is 'on the top of something else'. So we cannot say ''he is living on top of the road. Thus it is wrong.
• 'At' is used when we wish to give a particular point of place. Thus it is right.
• Therefore the answer is: He lives at 19 tower road.
