Option C
is the correct answer.
Explanatory Answer
IF Vial C tests positive while A, E, H are negative then any patient with vial A, E, H will not have the disease.
Patient 8 and 14 have E hence they are negative. Patient 2 doesn’t have vial C hence it can’t be positive.
Patient 6 has vial C and none of A, E, H.
