✓ Official correct answer
C
There is probably more product present than there is either substrate or enzyme.
D
The enzyme substrate complex is probably failing to form during the reaction

Explanation
When adding more substrate to a reaction increases enzyme activity, it indicates that enzyme was previously in excess relative to substrate — more enzyme molecules were available than there was substrate to bind, so extra substrate lets more of them catalyze the reaction.
