Yes, correct answer is C. Because cast iron is good in compression so it is used in column and large water pipes. However wrought iron pipe used for small size water pipes.

I think answer b is right.

C is the correct answer. I agree with the given option.

As cast iron is brittle in nature then wrought iron. So, the correct answer seems to be B.

Cast iron is used to water pipes etc.

It should not used to column and struts so answer B is correct.

The cast iron is good in compression because of high % of carbon, column and strut comprise a member that's why cast iron used in the column but column contain a huge amount of concrete, concrete take compressive load so why steel use for taking the compressive load. We all are known in a RCC member concrete take comp load and steel take tension. So, I think B is the right answer.

Cast-iron columns enabled architects to build tall buildings without the enormously thick walls required to construct masonry buildings of any height. Such flexibility allowed tall buildings to have large windows. In urban centres like SoHo-Cast Iron Historic District in New York City, manufacturing buildings and early department stores were built with cast-iron columns to allow daylight to enter. Slender cast-iron columns could also support the weight that would otherwise require thick masonry columns or piers, opening up floor spaces in factories, and sight lines in churches and auditoriums. The historic Iron Building in Watervliet, New York, is a cast-iron building.

So the answer is correct.

The Correct Answer is option B.

Sir tell me different between wrought iron and cast iron.

B is the correct answer. We are using Cast Iron pipes. And never seen CI columns.
