Answer:
The correct answer is: Quality of life
Explanation:
The dependent variable in analysis is the variable which cannot take any value by itself but the value it can assume depends on different independent variables which are related to it by a particular relation.
In the given case since it is given that "quality of life" depends on " functional ability or hearing acuity" thus we easily conclude that quality of life is a dependent variable since it depends on functional ability or hearing acuity.
