False sensory perceptions that often take the form of hearing voices are called a. delusions b. hallucinations c. obsessions d. compulsions

Option B, Hallucinations

Explanation:

Hallucination causes sensory perceptions in the absence of any external stimuli and hence these sensations are termed as false sensory perceptions. False sensations feel like extraordinarily natural and are different from delusion as they occur under sensory modality.  

They are extremely different from illusion where a person perceive a different scenario for an existing scenario while in case of hallucination a person perceives a scenario even when it do not exists.  

Hence, option B is correct

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
