Hint: Resistors are considered to be parallel connected as they are both connected to each other resistor or resistor terminal. Since the supply current travels across different routes, the current will not be equal through all branches of the parallel network.

Complete solution:
The resistance ends are connected at the same point in parallel connection. At the same time, both resistors have different connections, but voltage around the resistor stays the same as they are connected from the same place.

In an electric circuit, components may be arranged together in parallel, as resistive elements are mounted in a parallel circuit, the voltage around each resistor is the same. The current flows through the part and forms the current flow through the source. Also the polarities are the same, even as one component breaks down, other components have their own different circuit

In the domestic electric system the systems are connected in tandem because other units are not affected if one unit ceases operating or is fused. In addition, all electrical equipment have equal voltage at the same time. This helps to install the machinery.

The correct option is D.

Note: However, in a parallel suburban network the voltage decreases over both resists. Then in parallel, resistors have a common voltage through them, which is true for all connected parallel components. Thus, a parallel resilient circuit may be described by attaching resistors to the same two (or nodes) points and by realising that it has multiple current paths connected to a common voltage source.
