Final answer:
Pseudoscience is best described by explanations that do not have experimental support. It refers to claims presented as scientific without adhering to scientific standards like empirical evidence and reproducibility, unlike genuine scientific theories which are well-supported by evidence and peer review.
Step-by-step explanation:
The best description of pseudoscience is explanations that do not have experimental support. Pseudoscience is a claim, belief, or practice that is presented as scientific but does not adhere to the rigorous standards and methods of science, such as empirical evidence and reproducibility. This means that pseudoscientific claims are not supported by a methodical collection of experiments and do not undergo the critical peer review process that is fundamental in genuine science.
Scientific theories, on the other hand, are well-substantiated explanations of phenomena in the natural world that are supported by a considerable body of evidence gathered through repeated testing and observation. Theories are subjected to peer review and are based on empirical evidence, which is crucial for a claim to be regarded as scientifically valid.
Therefore, in the context of the options provided, pseudoscience is indeed associated with explanations that lack experimental support and do not meet the stringent criteria of the scientific method.
