Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 17.593\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a COC(=O)c1cc(C#N)c(N2CC(C)OC(C)C2)nc1C
b Cc1c(CBr)[n+](=O)c2c(n1[O-])C(Br)CCC2Br
c C[C@@H](NC(=O)[C@@H]1Cc2ccccc2CN1)C(=O)NCC1CCCO1
Answer: b. Cc1c(CBr)[n+](=O)c2c(n1[O-])C(Br)CCC2Br
