Which of the following circuits has both series and parallel characteristics?

A series-parallel circuit is characterized by having components arranged in both series and parallel configurations. This means that some components are connected end-to-end (in series), while others are connected across common points (in parallel). This type of circuit allows for a more versatile design, enabling different paths for current flow and the ability to modify circuit behavior in terms of voltage and current distribution.

In contrast, an open circuit does not have a complete path for current to flow, while a short circuit typically allows current to flow unrestricted, posing a risk of damage or failure. A grounded circuit refers to a circuit that has a connection to the ground for safety or stabilization purposes but does not inherently imply a combination of series and parallel configurations. Thus, the series-parallel circuit stands out as the correct answer due to its inherent design that incorporates both circuit characteristics.
