The possible blood type of offspring, when a woman with type O and a man who is type AB are expecting a child are A and B.
There are four kinds of blood groups which are A, B, AB, and O, based on the presence of antigens in RBC. Blood groups A and B show co-dominance, while O is recessive.
When a woman with type O blood and a man who is Type AB are expecting a child, the possible blood types are A and B. 50% of the children would have A blood type, and 50% of children would have blood type B, which are heterozygous.
When Parents are both heterozygous for the B blood group, then the possible blood group of offspring would be 75% B blood type (25% are homozygous and 50% are heterozygous) and 25% O blood type.

A control is a variable-independent element. Therefore, option (A) sunlight is the control used as a point of comparison.
Experiments and observations in the field of science that are designed to reduce the influence of factors other than the one being studied are examples of scientific controls. This makes the results more reliable, most commonly by allowing a comparison to be made between the control measurements and the other measurements.
Controls reduce the effects of other factors on the experiment. It verifies an experiment's claim. Controls are needed for all experimental testing, not just science.
Therefore, sunlight is used as control because its a natural source of light and most plant grows in it.
