Which of the following is one of the main characteristics of a pseudoscientific claim?

A. The claim doesn't originate from a scientific hypothesis.
B. The inability of the claim to be expressed in a mathematical equation.
C. The lack of any possible test which could falsify the claim.
D. The claim deals with something already debunked, such as astrology or crystal power.

Falsifiability is crucial to distinguishing between scientific claims and pseudoscience like astrology, which lacks testability and falls outside the realm of science.

Explanation:

Falsifiability is a key characteristic of a pseudoscientific claim, as it distinguishes scientific claims from pseudoscience. Pseudoscientific claims lack the ability to be tested and falsified, making them unscientific. For example, claims like astrology, which attribute celestial movements to human behavior without experimental evidence, fall into the realm of pseudoscience due to their untestable nature.
