Statement I is incorrect. The Golgi cisternae are not concentrically arranged; they are arranged in a cis-to-trans direction, with the cis face receiving proteins from the endoplasmic reticulum and the trans face releasing modified proteins.
Statement II is also incorrect. Protein modification occurs in the cisternae of the Golgi complex as they move from the cis to the trans face, not just at the cis face.

A | Axoneme | I | Centriole |

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 the dipole of dipole moment vector
\(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), 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 :
