Task: Answer the multiple choice question.
Query: Which drug exhibits a 18.300\% 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, or c without using any additional words.
Options:
a: Br.Cc1ccccc1Cn1c(=N)n(CC(=O)c2ccc([N+](=O)[O-])cc2)c2ccccc21
b: O=S(=O)(NCCSc1ccc(Cl)cc1)c1ccc(F)cc1
c: Cn1c(=O)c2c(nc(N/N=C/c3ccc(OC(=O)c4ccco4)cc3)n2Cc2ccccc2Cl)n(C)c1=O
Answer: b. O=S(=O)(NCCSc1ccc(Cl)cc1)c1ccc(F)cc1
