The right answer is A.

Enzymes play a central role in the regulation of biological processes. They generally consist of protein molecules derived from the translation of the genome, with the exception of ribozymes consisting of RNA. The enzymes intervene by decreasing the energy barrier between the reactants allowing to accelerate the reactions thousands of times more than in the absence of catalysis.

It is true that we can make the analogy between enzyme-substrate and lock-key. But we must take into account that the substrate will be transformed into a product, so the "key" will be somehow "deformed".

Gloria is experiencing pain in the upper right portion of her abdomen, has greasy diarrhea, and bleeds excessively when she mens
Volgvan
Bile

Based on the above symptoms, it can be inferred that Gloria lacks bile. Pain in the upper right portion of the abdomen usually corresponds to problems with the liver. The liver produces bile (also known as gall), which is a dark green to yellowish brown fluid that helps most vertebrates with digestion. It increases the absorption of fats and fat-soluble substances such as vitamins A,D,E, and K. It is also necessary for the excretion of bilirubin, which is a byproduct when red blood cells are recycled by the liver. 

Bile deficiency can cause the fats in the food to be undigested and these fats end up excreted as part of feces. It can also lead to vitamin deficiency and a gradual build-up of toxins in the liver.
