Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 23.454\% 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 Cl.O=C(O)c1cccc(Nc2nc(-c3ccccc3)nc3ccccc23)c1
b CC1=C(C(=O)Nc2ccccc2C(=O)NCCCOC(C)C)SCCO1
c Cn1cc(CN2CCCC(CO)(Cc3cccc(Cl)c3)C2)cn1
d CC1(C)C2CCC1(CS(=O)(=O)NCc1ccc(C(F)(F)F)cc1)C(=O)C2
e COc1cccc2c(=O)c(C(=O)NCc3cccs3)c[nH]c12
Answer: e. COc1cccc2c(=O)c(C(=O)NCc3cccs3)c[nH]c12
