Final Answer :
B
Explanation :
Light-blue-stoppered tubes must be completely full because they contain citrate, which acts as an anticoagulant by binding to calcium in the blood. The precise blood-to-anticoagulant ratio is crucial for accurate coagulation testing, hence the need for the tube to be completely full.
