Edna, age 71, has excellent pronunciation but poor spelling. She frequently forgets the word or phrase she is trying to use, telling others that it is on the tip of her tongue. These characteristics may be the result of:

A) decreased inhibition.
B) impaired vision.
C) inadequate control processes.
D) poor muscular coordination.

Explanation:

During late adulthood, control processes in an individual may tend to become weak as the process of neurotransmitter productions reduce and weaken in old age.This results in the delay of perceiving and processing sensations as neural transmission becomes weak and irregular.

Here, Edna who is aged 71 is in her late adulthood. Due to inadequate control of processes in her neurotransmitter, she may frequently forget the word or phrase she is trying to use.

Her control process of perceiving and processing sensations have become inadequate and irregular because of old age.
