TRANSMISSION OF VIRAL DISEASES, IMMUNOSUPPRESSION AND CIRCULATORY OVERLOAD
B
TRANSMISSION OF VIRAL AND BACTERIAL DISEASES.
C
TACO
D
NONE OF THE ABOVE
Explanation: 

Detailed explanation-1: -An increased incidence of postoperative infection and risk of cancer recurrence in patients who have received allogeneic blood transfusions suggests that such transfusions may be associated with clinically significant immunomodulatory effects.

Detailed explanation-2: -The risk of transfusion-associated circulatory overload increases with the number of blood products administered and a positive fluid balance, and in patients with pre-existing heart failure and chronic renal failure.

Detailed explanation-3: -Risk factors for TACO are diseases that increase the amount of fluid a person has, including liver, heart, or kidney failure, as well as conditions that require many transfusions. High and low extremes of age are a risk factor as well.
