A transfusion of type A blood given to a person who has type O blood would result in which of the following?

#Unit 4. Cell Communication and Cell Signaling
  1. the recipientʹs B antigens reacting with the donated anti-B antibodies

  2. the recipientʹs anti-A antibodies clumping the donated red blood cells

  3. the recipientʹs anti-A and anti-O antibodies reacting with the donated red blood cells if the donor was a heterozygote (Ai) for blood type

  4. no reaction because type O is a universal donor
