Task: Answer the multiple-choice question.
Question: Which drug exhibits a 13.356\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(Nc1ccc2oc(-c3ccncc3)nc2c1)c1c(F)c(F)c(F)c(F)c1F
(b) O=C(NC(=S)N1CCN(c2c(Cl)cccc2[N+](=O)[O-])CC1)c1cccs1
(c) O=C(CC1(O)C(=O)N(CCc2ccccc2)c2ccccc21)c1ccccn1
Answer: a. O=C(Nc1ccc2oc(-c3ccncc3)nc2c1)c1c(F)c(F)c(F)c(F)c1F
