Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.126\% 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, d, or e without using any other words.
Options:
(a) COc1ccc(NCC(=O)N/N=C/c2c(C)nn(Cc3ccccc3)c2Cl)cc1
(b) CCC(C)N1C(=O)/C(=C/c2c(NCCCOC(C)C)nc3c(C)cccn3c2=O)SC1=S
(c) CC1=CC(C)C(/C=N/n2cnnc2)C(C)C1
(d) COc1ccc(C(C)=O)cc1CSCC(=O)O
(e) CC1=C(C#N)C(NC(=O)c2ccco2)(C(F)(F)F)C(=O)N1
Answer: b. CCC(C)N1C(=O)/C(=C/c2c(NCCCOC(C)C)nc3c(C)cccn3c2=O)SC1=S
