A person with ARh- blood can receive blood from individuals with blood types that do not contain the anti-A antibody, anti-B antibody, or the Rh factor. The options are evaluated:
ARh- (D): Compatible, as it lacks A and B antigens and the Rh factor.
ORh- (C): Compatible, as it lacks A and B antigens and the Rh factor.
The other options have either A or B antigens, or the Rh factor, and are thus incompatible with ARh- blood.
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 :
