Blood groups can pass through one generation to another is discovered by :

  • A.Lutheran
  • B.Landsteiner
  • C.Dungern and Hirzfield
  • D.Epstein and Ottenberg

Answer: C

The inheritance of blood groups was shown by von Dungern and Hirszfeld (printed 'Dungern and Hirzfield').

Karl Landsteiner discovered the ABO blood groups in 1900-01, but the demonstration that they are inherited according to Mendelian rules came from Emil von Dungern and Ludwik Hirszfeld in 1910, from family studies. Their work laid the foundation for using blood groups in disputed paternity cases. Earlier, in 1908, Epstein and Ottenberg had suggested that blood groups might be inherited.

Landsteiner is the tempting choice because he discovered the groups, and Lutheran is the name of a blood group system, not a scientist.
