Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.474\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C(CN1C(=O)NC2(CCCCCC2)C1=O)NC1CC1
b: COc1ccccc1CN1CCN(Cc2nc(-c3cccs3)no2)CC1
c: CCCCCN(C(=O)CCC(=O)OCC(=O)Nc1ccc(C)cc1F)c1c(N)n(CCCC)c(=O)[nH]c1=O
d: Cc1ccccc1-c1nnc2c3ccccc3c(C)nn12
e: COc1ccc(C2NC(c3ccc(OC)cc3OC)C(C)C(=O)C2C)c(OC)c1.O=C(O)C(=O)O
Answer: a. O=C(CN1C(=O)NC2(CCCCCC2)C1=O)NC1CC1
