Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.471\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C1/C(=N\S(=O)(=O)c2cccs2)C([n+]2ccccc2)=C([O-])c2ccccc21
b Cn1c(=O)c2sccc2n2c(CCCC(=O)NCc3ccco3)nnc12
c CSc1nnc(CSc2cc(C)nc(N(C)C)n2)o1
d Oc1c(Br)cc(C2N=C(c3ccccc3Cl)NO2)cc1Br
Answer: d. Oc1c(Br)cc(C2N=C(c3ccccc3Cl)NO2)cc1Br
