This is an experimental study because the researcher is manipulating a variable (forcing the rats to take a particular direction) and then observing the effects on the outcome variable (the time it takes to complete the maze). The other options don't fit because an observational study would simply observe rats going left and right without any manipulation, and a longitudinal study would follow the same group of rats over a period of time.
