Which quality would researchers in psychology ascribe to good theories?

As with any scientific research the quality of the theory depends on several factors. Here first thing to mention is that of course it needs to be organized as in organizing the observations clearly imply the results. The second important thing is the results need to be crystal clear and they need have predictions that with good testing should be predictable and acquired with each testing.

Ithink the answer is b. shakeri hope im not wrong : )
