The search for knowledge in science is based on the scientific method, in which a hypothesis is raised and through experiments, it is accepted or rejected. Pseudoscience does not apply the scientific method.
Let's analyze each of the options
B. Science can be questioned, sometimes a theory can be taken as true, but other scientists have come to show that it is not true. For example, heliocentrism and geocentrism. So, option is B is false
C. Science is based on systematic measurements. So, option is C is false.
D. Science is not based on absolute truths. A theory that may be accepted as true today may be proven false in the future. So, option is D is false.
A. Science bases its claims on testable evidence, while pseudoscience does not. Correct option
The answer is option A.
