Answer 1

Answer:

B. Weber's law.                                                                                              

Explanation:

Weber's law: The Weber's law is also known as the Weber-Fechner law and is defined as the size of JND i.e, just noticeable difference (represented with delta I) is of constant proportion to that of the value of the original stimulus. In other words, the law states that the increment threshold ratio concerning the background intensity is similar.

Example: A person needs to shout to be heard by the person in any noisy place.

In the question above, the given statement best illustrates the Webers's law.
