Electrostatic Potential and Capacitance

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: The potential $V$ at any axial point, at 2 m distance $r$ from the centre of a dipole of dipole moment $\vec{p}$ of magnitude $4\times 10^{-6}$ C m, is $\pm 9\times 10^3$ V. (Take $\frac{1}{4\pi {\epsilon }_0}=9\times 10^9$ SI units.)

Reason R: $V=\frac{1}{4\pi {\epsilon }_0}\frac{2p}{r^2}$, where $r$ is the distance of any axial point, situated at 2 m from the centre of the dipole.

In the light of the above statements, choose the correct answer from the options given below:
