Task: Answer the multiple-choice question.
Question: Which compound exhibits a 4.181\% 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: O=C(CCCNS(=O)(=O)c1cccc2nsnc12)NCCc1ccccc1
b: CCOC(=O)c1c(NC(=O)/C=C/c2ccc(C)o2)sc(C)c1C
c: O=C(Nc1ccc(N2CCCC2=O)cc1)c1cccc(F)c1
Answer: b. CCOC(=O)c1c(NC(=O)/C=C/c2ccc(C)o2)sc(C)c1C
