You complete blood type testing and there is no agglutination with either anti-A, anti-B or anti-Rh antibodies. What type of blood is present?
Type AB+
Type AB-
Type O-

Persons with Type AB blood produce both anti-A and anti-B antibodies.
Persons with Type AB blood produce neither anti-A and anti-B antibodies.
Persons with Type AB blood produce only anti-B antibodies.
Persons with Type AB blood produce only anti-A antibodies.
