Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.217\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COc1ccc(S(=O)(=O)N2CCCCC2)cc1NC(=O)CCNC(=O)c1ccccc1Cl
b: COc1cc(C(=O)N=c2sc3ccccc3n2C)cc(OC)c1OC
c: CCOC(=O)C1=C(C)N=C2SCCC(=O)N2C1c1cc(Br)ccc1OC
Answer: c. CCOC(=O)C1=C(C)N=C2SCCC(=O)N2C1c1cc(Br)ccc1OC
