Task: Answer the multiple-choice question.
Query: Which drug exhibits a 9.728\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) CN1C(=O)CC(N2CCN(c3ncccn3)CC2)C1=O
(b) Cc1ccc(-c2nc(=O)[nH]c3ccc(Br)cc23)cc1
(c) CCOc1ccccc1CN1CCN(Cc2cn(C)nc2-c2ccccc2)CC1CCO
(d) Cc1ccnc(NC(=O)C2CCC(CNc3c(N4CCCC4)c(=O)c3=O)CC2)c1
(e) CC(=O)Nc1ccc(C(=O)Nc2nc(-c3ccccn3)cs2)cc1
Answer: a. CN1C(=O)CC(N2CCN(c3ncccn3)CC2)C1=O
