Answer:

Option C

Explanation:

Complete question

Which term describes the perception of the body's movement through space?

A. nociception

B. neurasthenia

C. kinesthesia

D. dimensionality

This is also related with the Charles bell concept of sixth sense through which one could perceive sensation of static position or velocity of the movement

 Hence, option C is correct

Set I – White fly nymphs with translucent bodies  

Set II- White fly nymphs with translucent bodies coated with harmless dyes.  

The number of predated flies in each set can be compared to deduce justification for assumed hypothesis.  

Hence, option B is correct
