Task: Answer the multiple choice question.
Query: Which drug has a 18.287\% 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] CC1CCCCN1C(=O)CN(C)S(=O)(=O)c1cccc2nsnc12
[b] COc1cc(C(=O)N/N=C(\C)Cc2ccccc2)cc(OC)c1OC
[c] Cl.O=C(NCCNCCO)c1c(O)c2cccc3c2n(c1=O)CCC3
Answer: b. COc1cc(C(=O)N/N=C(\C)Cc2ccccc2)cc(OC)c1OC
