The answer is B, multiple alleles.
Codominant is when the gene pair in a heterozygous are both fully expressed.
Incomplete dominance is when one allele is not fully expressed over its paired allele.
The exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
