C
Type O
D
either Type B or Type O
Explanation: 

Detailed explanation-1: -Blood group O has no antigens, but has both anti-A and anti-B antibodies in the plasma, as well as some special “anti-A, B” antibodies. Blood group AB has both A and B antigens, but no antibodies. Blood group B has B antigens with anti-A antibodies in the plasma.

Detailed explanation-2: -Anti-A and anti-B are found in the sera of individuals who lack the corresponding antigens. They are produced in response to environmental stimulants, such as bacteria, and have therefore been termed natural antibodies.

Detailed explanation-3: -The Anti-A, Anti-B, and Anti-A, B reagents are used in the red blood cell determination of the ABO blood group. They are used to determine the absence or presence of erythrocytic antigens A and/or B on the surface of human red blood cells.
