Task: Answer the multiple choice question.
Query: Which compound exhibits a 14.995\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O=C1NC(=O)C(CCc2ccncc2)(Cc2ccc([N+](=O)[O-])cc2)C(=O)N1
[b] N#C/C(=C\c1cccnc1)c1nc2ccccc2[nH]1
[c] Cc1cccc(N2CCN(S(=O)(=O)c3ccc4[nH]c(=O)c(=O)[nH]c4c3)CC2C)c1
[d] COc1ccc(OC)c(NS(=O)(=O)c2ccc(Cl)nc2)c1
Answer: a. O=C1NC(=O)C(CCc2ccncc2)(Cc2ccc([N+](=O)[O-])cc2)C(=O)N1
