Point A You have given the definition of electric circuit. An electrical circuit is basically a closed path through which current flows. In an electric circuit the current will return to the source from which the current flows. But there can be one or more paths. In case of series circuit there is one line of current flow and in parallel circuit there are multiple paths of current flow. The electrical circuit requirements mentioned are two but you can specify more. Load management, voltage and current distribution, power measurement etc. (1)

In point B you present the differences quite well.Here the resistances of parallel circuit are placed in parallel. In a series circuit the voltage is divided and the current remains the same. The total voltage of a parallel circuit and the voltage across each resistance are the same. Series circuit has one path of current flow and parallel circuit has multiple paths. You should know these differences. The results of both the circuits you solved are correct. (3.2)

The continuity of the cable joint has been presented very well. Your attention can be fully focused on the cable connection. The details of the connecting moments were clear. (3)

We are glad to know that you are learning something. You have presented your subjects very sweetly. What you learn about the concept of electrical circuits and cable joints is enough to express your opinion. (1.5)
