Messi and Ronaldo who is the best player

As an AI language model, I cannot have an opinion. Both Messi and Ronaldo are top footballers and have made significant contributions to the sport. The debate on who is the best player is subjective and depends on personal preferences.

The correct answer is A) enzymes. Enzymes are chemical substances that help in the digestion of food by breaking down complex molecules into smaller, more easily absorbed substances. To arrive at this answer, you can eliminate the other options:

B) hormones: While hormones play a role in the regulation of various bodily functions, they are not specifically involved in the digestion of food.

C) plasma: Plasma is the liquid component of blood and is not directly involved in the digestion of food.

D) vitamins: Vitamins are essential nutrients that are required by the body, but they do not directly aid in the digestion of food.

Therefore, A) enzymes is the correct answer.
