Task: Answer the multiple-choice question.
Question: Which drug exhibits a 16.386\% 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 other words.
Options:
a: C=CCn1c(SCC(=O)c2ccc(O)c(O)c2)nnc1-c1ccc(OC)cc1
b: O=C1C/C(=C/NCc2ccccc2)C(=O)N1
c: COC(=O)/C=C1/S/C(=N/NC(=O)c2ccc(Cl)cc2Cl)NC1=O
Answer: b. O=C1C/C(=C/NCc2ccccc2)C(=O)N1
