Pitch (a product of coal tar distillation) is always mixed with creosote oil, when it is to be burnt in a burner, because

A Its calorific value is very less
B Tar neutralises the residual acids present in pitch
C It reduces viscosity and imparts fluidity for its transportation through pipelines at economic pressure drop
D All of the above

Correct Answer: It reduces viscosity and imparts fluidity for its transportation through pipelines at economic pressure drop
