Task: Answer the multiple choice question.
Query: Which compound has a 18.941\% 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(O)C(=O)O.O=C1CC(Cc2ccccc2)C(=O)N1CCCn1ccnc1
b O=C(Nc1nnc(S(=O)(=O)N2CCCCCC2)s1)c1ccc(Cl)cc1
c COc1ccc2nc(-c3ccc(F)cc3)sc2c1
Answer: b. O=C(Nc1nnc(S(=O)(=O)N2CCCCCC2)s1)c1ccc(Cl)cc1
