b
Step-by-step explanation:
Part (a)
Independent variable = age
Dependent variable = height
"depends on age" indicates that age is independent.
-----------------------------------
Part (b)
Independent variable = amount of sleep
Dependent variable = mood
The key word is "determines". The stuff before this word is the independent variable which affects the dependent variable.
-----------------------------------
Part (c)
Independent variable = time water has been running
dependent variable = amount of water in the tub
Time is usually the independent variable
-----------------------------------
Part (d)
Independent variable = speed
dependent variable = distance from home
-----------------------------------
Part (e)
Independent variable = amount of homework done
dependent variable = speed

-----------------------------------
Part (f)
Independent variable = amount of hw that is assigned
dependent variable = amount of homework done
Like with part (a), the stuff before "depends" is the dependent variable
