A uniform electric field pointing in positive $x$-direction exists in a region. Let $\mathrm{A}$ be the origin, $\mathrm{B}$ be the point on the $x$-axis at $x=+1 \mathrm{cm}$ and $C$ be the point on the $y$-axis at $y=+1 \mathrm{cm}$. Then the potentials at the points $\mathrm{A}$, $\mathrm{B}$ and $\mathrm{C}$ satisfy the condition
