The type of changes that created the cake and the icing is;

Option D; The cake is formed by a chemical change and the icing is formed by a physical change.

This is about understanding type of changes in chemistry.

Physical change is defined as a change that affects the form of a compound or element but it doesn't affect its' chemical composition.

Meanwhile, chemical change is defined as a change that affects the composition of a compound and a new substance is formed.

Now, for brian's cake he has combined raw ingredients into two pans and bakes the cake. For the cake to be baked, it means the ingredients mixed have changed from liquid to solid and also a new substance has been formed. Thus, we can say that the cake was formed from chemical change.

Meanwhile, the icing was formed by physical change because it did not undergo any chemical process and no new substance was formed as only butter, sugar and milk were mixed together.
