Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.965\% 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(NC1CC1)C1CCN(C(=O)c2ccc(Cl)cc2Cl)CC1
(b) CCCn1c(COc2ccccc2OC)nc2ccccc21
(c) O=C(Nc1ccc2nc3n(c(=O)c2c1)CCCC3)c1cccnc1Cl
Answer: c. O=C(Nc1ccc2nc3n(c(=O)c2c1)CCCC3)c1cccnc1Cl
