Answer :
This is more aligned with the theory of (C) 4 plus or minus 1 rather than Miller's original 7 plus or minus 2 concept.
In 1956, George Miller proposed the concept of the magic number "7 plus or minus 2" based on short-term memory capacity, suggesting that people could recall between 5 to 9 items. However, more contemporary research, such as Cowan's study in 2010, suggests that the working memory capacity is closer to "4 plus or minus 1".
Therefore, in real-world settings, most people can hold about 4 items in their working memory.
