Answer: C. warfarin.

Explanation:

Warfarin has been the cornerstone of oral anticoagulant therapy for about 50 years. Its effectiveness has already been proven in the prevention of venous thromboembolism in the prevention of systemic embolism in patients  with cardiac valve prostheses or atrial fibrillation and the prevention of acute myocardial infarction (MI) in high-risk men. Warfarin mainly inhibits the vitamin K epoxide reductase enzyme, which prevents the cyclic interconversion of this vitamin. This way, by blocking the cyclic interconversion of vitamin K prevents carboxylation of glutamate residues in terminal regions in K-dependent proteins.  Warfarin is the most commonly used oral anticoagulant in clinical practice and is composed of two isomers, R-warfarin, and S-warfarin (5 times more potent than R-isomer), which are metabolized in the liver by different routes.

Pseudoscience may sometimes permit personal opinions as evidence.

<h3>What is pseudoscience?</h3>

The term pseudoscience refers to the reliance on logical explanations rather than empiricism to explain the observations in the universe. We know that science is empirical and results must be reproducible.

It is important to emphasize that the difference between science and pseudoscience is that science has an emphasis on empiricism and experiments are the only way that we could validate. Most of the earliest approaches to the study of the universe depended on pseudoscience.

The study of the natural world is the concern of both science and pseudoscience. The explanations in pseudoscience may sound logical but the results generated by science can be tested by others. The explanations of science can be proven false.

Lastly pseudoscience may sometimes permit personal opinions as evidence.
