Q1:

Wrought iron contains carbon about

A 1.5% to 5.5%

B 0.5% to 1.75%

C 0.1% to 0.25%

D none to these.

ANS:C - 0.1% to 0.25%

Wrought iron is an iron alloy with a very low carbon (less than 0.08%) content in contrast to cast iron (2.1% to 4%).

It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which gives it a "grain" resembling wood that is visible when it is etched or bent to the point of failure.
