73. According to the latest NIST (National Institute of Standards and Technology), usersshould focus on password’s length, as opposed to its complexity. Actually, NISTdiscourage users to use passwords which mix numbers, capitalization and specialcharacters. Which one of the following is NOT the reason why NIST makes thisrecommendation？
(A)Complex memorized secrets are less likely to be memorable
(B)Increasing length can improve the password entropy more than increasingcomplexity
(C)If users need to follow the password complexity guideline, users’ password choicesmay be very predictable
(D)Considering the IoT era, some devices cannot provide an input device large enoughto contain all special characters
