The circuit diagram contains two resistors with resistances of $10\,\text{k}\Omega$ and $50\,\text{k}\Omega$, together with a component $Y$. A $6.0\,\text{V}$ power supply is applied. The electric potential of the lower wire is $0\,\text{V}$. The current in component $Y$ is negligible. What is the electric potential at junction $X$?
- A$1.0\,\text{V}$
- B$1.2\,\text{V}$
- C$4.8\,\text{V}$
- D$5.0\,\text{V}$
