I E. Data gathered during experiments show that there is an inverse

The correct options are A and B

Explanation:

Personal beliefs can be described as beliefs that have not been scientifically proven. These beliefs are generally as a result of religion, culture or tradition. Scientifically in theory, these beliefs lack clear path of possibility. For example, being in possession of certain mineral crystals in order to help protect the body against illness have a little possibility of being scientifically (in theory) explained. There is also no scientific evidence to support this claim.

There is also no scientific evidence to support the idea of the constellation's position to predict  events in a person's life. This also has little possibility of being theoretically explained in science.

It should however be noted that there are exceptions/coincidences that suggest these events happen as it has been listed in the two options.
