The main difference between a series and a parallel circuit is that

Amore components can be added to a parallel circuit.
Bthe voltage source for a series circuit can be weaker.
Cin a series circuit there's only one path for current to flow.
Da parallel circuit can handle components with higher resistances.

Verified Answer :

Cis correct

series circuit - in the same path : current flow on one path so they are equal on each component and equal to the source's. voltage on each components may be different.

parallel circuit - between same nodes : voltage of the components are equal and equal to the source's. current on each components may be different.
