Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.868\% 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(NN1C(=O)c2ccc(-c3ccc4c(c3)C(=O)N(NC(=O)c3cccnc3)C4=O)cc2C1=O)c1cccnc1
(b) COc1ccc(NC(=O)Nc2ccc3c(c2)CCC3)c(OC)c1
(c) O=C(Nc1ccc(N2CCCC2)cc1)c1ccccc1[N+](=O)[O-]
Answer: a. O=C(NN1C(=O)c2ccc(-c3ccc4c(c3)C(=O)N(NC(=O)c3cccnc3)C4=O)cc2C1=O)c1cccnc1
