Lara's mouth is dry and she realizes that she hasn't had anything to drink all morning. the water level in her cells has dropped and she feels thirsty. watching people drink large glasses of soda is driving her nuts, so she determines that the next chance she gets, she will get an extra-large drink. which of the following can be used to explain why she is motivated to get a drink?
a. drive-reduction theory
b. set-point theory
c. human factor
d. basal metabolic rate

Lara is motivated to get drink because of drive-reduction theory.

Option A

The state of "tension or arousal" due to  biological or physiological needs is a drive reduction theory.

For example: Hunger, Thirst

It happens because there are some basic needs of human body. Human body requires to eat, drink, sleep. These are the basic needs for humans and it is very important to fulfill them. So clearly thirst is one of them so when we feel thirsty we just want to have a glass of water or may be some other sort of drink to quench our thirst.

So these are biological needs. When we are thirsty our cells dried and because of that our throat started feeling dry. This is why water is needed to keep hydrating our cells and keep them working completely.
