Answer: (c) Context Effect
Explanation: Context Effect is an aspect of cognitive psychology which describes how environmental factors afects a person's perception of stimuli. It is known to occur at all scales at which words may be viewed. It is supported by constructive perception, the effect of a context perception is known to be part of a top-down design, the view of the moon through a narrow tube which has affected the perception of the viewer who now see the moon as shrinking in size is a context perception.
Answer:
(a) 
Explanation:
We have given speed of light 
Given time = 1 year =365 days
We know that in 1 minute = 60 sec
1 hour = 60×60 = 3600 sec
In one day = 24 hour = 24×60×60=86400 sec
So in 365 days = 365×86400
We know that distance = speed ×time
We have given that 1 mi = 1609 m
So
So option (a) is correct
The smallest size of the insect that the bats can detect corresponds to the wavelength of the chirp they emit.
Their chirp has a frequency of

and the speed of the chirp is equal to the speed of sound in air:

Therefore the wavelength of the chirp is

which corresponds to a size of 4.76 mm.
