Task: Answer the multiple choice question.
Question: Which compound exhibits a 18.003\% 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. CCOC(=O)c1c(NC(=O)c2cccs2)sc2c1CC(C)(C)OC2
b. O=C(Nc1ccccc1)Nc1nc(-c2ccc(Cl)cc2)cs1
c. O=C(CCC1CCCCC1)NCCN1C2=NC[C@H](Cc3ccccc3)N2C[C@H]1Cc1ccc(O)cc1
Answer: b. O=C(Nc1ccccc1)Nc1nc(-c2ccc(Cl)cc2)cs1
