Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 12.792\% 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. COC(=O)c1ccc(S(=O)(=O)N2CCC(O)CC2)n1C
b. O=C(/C=C/c1cc2ccccc2o1)c1ccccc1O
c. CC(C(=O)N/N=C/c1ccc(N(C)C)c(Br)c1)N(c1ccccc1)S(C)(=O)=O
Answer: b. O=C(/C=C/c1cc2ccccc2o1)c1ccccc1O
