Task: Answer the multiple choice question.
Question: Which compound has a 1.815\% 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: CCOC(=O)C(=O)N1CCN(c2cc3c(cc2[N+](=O)[O-])n(C)c(=O)n3C)CC1
b: S=C(NCCc1ccccc1)N/N=C/c1ccccc1Cl
c: Cc1cc(Nc2cccc(C(=O)O)c2)n2ncnc2n1
d: CCc1ccc(-c2ccc3nnc(SC)n3n2)cc1
e: CCOC(=O)C1=C(C)Nc2sc(C(=O)c3ccc(Br)cc3)c(N)c2C1c1ccc(C(=O)OC)cc1
Answer: d. CCc1ccc(-c2ccc3nnc(SC)n3n2)cc1
