B
Unitentional Blindness
C
Absolute Threshold
D

Explanation: 

Detailed explanation-1: -The “absolute threshold of sensation” refers to the minimum intensity of a stimulus that a person can detect half the time. This threshold is not fixed, but varies from person to person and can be influenced by psychological factors, such as expectations, motivation, and alertness.

Detailed explanation-2: -Stimuli below the absolute threshold can still have at least some influence on us, even though we cannot consciously detect them. A variety of research programs have found that subliminal stimuli can influence our judgments and behaviour, at least in the short term (Dijksterhuis, 2010).

Detailed explanation-3: -An absolute threshold is the smallest amount of stimulation needed for a person to detect that stimulus 50% of the time. This can be applied to all our senses: The minimum intensity of light we can see. The lowest volume of a sound we can hear.

Detailed explanation-4: -D) The absolute threshold is defined as the minimum amount of stimulation necessary for a stimulus to be detected 60 percent of the time.
