Answer
In the first figure, elements C, D, and E are in parallel. In the second figure, there are no elements in parallel.
Work Step by Step
Recall, whereas all electrons go through all elements in series, electrons have the option of which element to go through in parallel. Consider the analogy of a road. If a car were driving through two elements in series, it would be like a road with no forks in it, meaning that the car would have to go through all elements. Contrarily, parallel elements are like a fork in the road, where the car has the option where to go. Using this, we find that in the first diagram, elements $\fbox{C, D, and E}$ are in parallel. In the second figure, we find that $\fbox{no elements are in parallel}$.
