Task: Answer the multiple choice question.
Query: Which drug exhibits a 11.428\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) O=C(C(=C1NCCN1)n1cncn1)c1ccccc1
b.) CCCn1c(SCc2ccc(Cl)cc2)nc2c1c(=O)[nH]c(=O)n2C
c.) O=C(NNS(=O)(=O)c1ccccc1)C1CC(c2cccnc2)=NO1
Answer: a. O=C(C(=C1NCCN1)n1cncn1)c1ccccc1
