Best answer
The correct choice is (b) SnCl2

To explain: During tinplating, a small quantity of the tin–iron compound FeSn2 is formed; the weight and structure depend on the time and temperature, as well as other factors such as the surface condition of the steel. The structure and weight of this alloy layer plays an important role in several forms of corrosion behavior.
