Answer 1

Right option is (b) Galvanized steel pipes

Easy explanation: Galvanised steel pipes (with circumferential corrugations) are much stronger than ordinary steel pipes. These are usually manufactured in various sizes varying from 20 cm to 2 meters in diameter. They are lighter and can be more easily transported at distances and are widely used where large pipes of smaller wall thickness are required.
