Answer 1

The correct option is C gum forming tendency & thoroughness of refining.

It tells us about the quality of gasoline whether there is some contamination present or the gasoline obtained is of low quality. The colour also shows us the indication whether it has gone through some chemical change. It shows gum forming tendency and thoroughness of the refining process.
