Task: Answer the multiple choice question.
Question: Which drug exhibits a 18.021\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CC(C)CN(Cc1c(O)ccc2ccccc12)CC(C)C
(b) O=C(O)C1CCCN1C(=O)Nc1ccc(F)cc1
(c) O=C(O)CCNc1c([N+](=O)[O-])cc([N+](=O)[O-])c2ccccc12
(d) CC(=O)c1c(C)nc2ccccn12
Answer: a. CC(C)CN(Cc1c(O)ccc2ccccc12)CC(C)C
