Identify the incorrect statements regarding blood groups:
Statements:
(1) The mother with Rh\(^{-}\) blood group develops passive immunity on administering IgM antibodies.
(2) Isoagglutinogens are sugar polymers bound to fatty acids on the RBC membrane.
(3) The alleles for Rh factor are located on three different loci on chromosome pair 9.
(4) The expression of ABO blood types in man is by three alleles of a single gene.

Show Hint
- II, IV
- I, II
- I, III
- II, III
The Correct Option is C
Solution and Explanation
Evaluating statements for accuracy.
Statement I is incorrect because Rh-negative mothers develop active immunity by producing IgG antibodies, not IgM, upon exposure to Rh-positive blood.
Statement III is incorrect as the Rh factor is determined by genes at a single locus, not multiple loci.
