Are claims about the effects of meditation most likely scientific or pseudoscience

The complete question is as follows:

Are claims about the effects of meditation most likely scientific or pseudoscientific?

A. scientific, because people have been claiming for thousands of years that meditation helps them

B. scientific, because observations of brain growth and chemicals are made carefully and repeatedly

C. pseudoscientific, because practices that are related to religion are based on beliefs and are subjective

D. pseudoscientific, because people have made claims about it but scientific observations have not been made

Option B, scientific, because observations of brain growth and chemicals are made carefully and repeatedly .

Explanation: Since observations have been made from time to time and same results were obtained, we can't say its pseudo-scientific. People have made claims about the effects of meditation and what it does to the brain activity. Thus, we would say meditation is a scientific process. Also, since brain activities were recorded, option B is correct.

looks like the answer is     c     to me!

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
