26/45\ntwo types of circuits are\nparallel and magnetic\nelectromagnetic and series\nseries and…

Brief Explanations:

In electrical - circuit theory, the two fundamental types of circuits are series and parallel circuits. Series circuits have components connected end - to - end with the same current flowing through them, while parallel circuits have components connected across common points with the same voltage across them. Magnetic and electromagnetic are not types of basic circuit configurations in this context.

Answer:

C. series and parallel
