The placebo effect
Explanation:
The placebo effect in psychology refers to a situation in which participants in a research receive beneficial effects due to the administration of an inactive substance or a sham treatment.

Answer: C. False colors are added to images to make some structures more noticeable.
False color refers to the special photography condition. This technique utilizes visible light range of the elctromagnetic spectrum to develop photograph. A false color image depicts an object in colors that differs from the actual color of the objects. This is used to capture the image of objects which cannot be detected in normal photographic techniques. It is a potent aerial photographic technique, which is used to capture large area of a region. It gives a definite color to vegetation, soil cover, river and other water body in the image.
False colors are added to images to make some structures more noticeable is the most accurate option because of the following reasons:
1. Electron microscope does not use beam of light to develop image but focuses beam of electrons to develop image.
2. Compound microscope does not use beam of electrons to develop image.
4. Electron microscope cannot be used for observation of living organisms, as high energy electron beam to develop image will be lethal for these living organisms.
