Task: Answer the multiple choice question.
Question: Which drug exhibits a -66.743% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. O=C(Nc1ccc(C(=O)N2CCN(c3ccccn3)CC2)cc1)c1ccc(Br)o1
b. Cn1c(=O)c2c(ncn2CC(=O)N/N=C/C=C/c2ccco2)n(C)c1=O
c. CCOC(=O)c1cnc2c(Cl)c(Cl)ccc2c1NCCN1CCOCC1.Cl
Answer: a. O=C(Nc1ccc(C(=O)N2CCN(c3ccccn3)CC2)cc1)c1ccc(Br)o1
