Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -20.392% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(C1CCN(S(=O)(=O)c2ccccc2[N+](=O)[O-])CC1)N1CCOCC1
b: O=C(NCCN1CCCC1)c1ccc2nc(-c3ccccc3)c(-c3ccccc3)nc2c1
c: CCc1ccccc1NC(=O)CN(c1ccc(OC)cc1OC)S(=O)(=O)c1ccccc1[N+](=O)[O-]
Answer: b. O=C(NCCN1CCCC1)c1ccc2nc(-c3ccccc3)c(-c3ccccc3)nc2c1
