Lara is motivated to get drink because of drive-reduction theory.
Option A
Step-by-step explanation:
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.
