Aperson's ability to quickly reason increases into early adulthood and fades in late adulthood. this is an example of how development is: a. static. b. multidirectional. c. pliable. d. multidimensional.

The correct answer is option B, that is, multidirectional.  

Development is multidirectional, signifying that modification takes place in every orientation, with losses and gains, predictable growth, and unanticipated changes being ostensible. Each characteristic of life, involving social interactions, intellectual growth, and physical health are multidirectional (down, up, irregular, or constant).  

In supplementation, in late adulthood, at the time of old age, the individuals seem to center on the declines in spite of the gains, putting a specific essential focus on multidirectional variation.
