Task: Answer the multiple-choice question.
Question: Which drug exhibits a 17.416% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) O=C(c1ccccc1)C(O)c1ccccc1
(b) O=C(c1cccc(S(=O)(=O)N2CCOCC2)c1)N1CCCc2ccccc21
(c) Nc1cccc2c1C(=O)N(C(=O)c1ccccc1Cl)C2=O
Answer: a. O=C(c1ccccc1)C(O)c1ccccc1
