Task: Answer the multiple choice question.
Question: Which drug has a -4.464\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CCOc1ccc(C2C(C#N)=C(N)SC(N)=C2C#N)cc1OC
b COc1cc(NC(=O)CN2C(=O)COc3ccc(S(=O)(=O)N4CCOCC4)cc32)cc(OC)c1
c CSc1nc(N2CCOCC2)c2c3c(sc2n1)CCC3
d O=c1c2sccc2nc(SCc2cc(=O)n3ccccc3n2)n1-c1ccc(Br)cc1
Answer: d. O=c1c2sccc2nc(SCc2cc(=O)n3ccccc3n2)n1-c1ccc(Br)cc1
