John is Making a chocolate mousse cake. The recipe calls for 2 cups of chocolate, 1 stick of butter, and 5 eggs. John decides to
use margarine instead of butter. What Kind of Mutation does John's version of the recipe best represent?
A. Deletion
B. Insertion
C. Substitution
D. Transition
Explain please
Substitution means switching or taking something else instead of something which can serve the purpose.
According to the meaning of Substitution, we can see that in the question it says that he INSTEAD used Margarine, and that means that he used something else instead of something which CAN serve the purpose.
And those were the reasons why that's your answer!
