Which of the following equations depicts Verhulst-Pearl logistic population growth?
$\frac{\mathrm{dN}}{\mathrm{dt}}=\mathrm{rN}\left(\frac{\mathrm{K}+\mathrm{N}}{\mathrm{K}}\right)$.
$\frac{\mathrm{dN}}{\mathrm{dt}}=\mathrm{rN}\left(\frac{\mathrm{K}-\mathrm{N}}{\mathrm{K}}\right)$
$\frac{\mathrm{dN}}{\mathrm{dt}}=\mathrm{rN}\left(\frac{\mathrm{K}-\mathrm{N}}{\mathrm{N}}\right)$
$\frac{\mathrm{dN}}{\mathrm{dt}}=\mathrm{rN}\left(\frac{\mathrm{K}}{\mathrm{K}-\mathrm{N}}\right)$

B. Rh antigen is observed on RBCs in the majority of human beings.
C. Before blood transfusion, Rh group should also be matched.
D. Rh incompatibility is observed when a pregnant mother is $\mathrm{Rh}^{-\mathrm{ve}}$ and the foetus is $\mathrm{Rh}^{+\mathrm{ve}}$.
