Task: Answer the multiple choice question.
Query: Which compound exhibits a 12.350\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: Cn1c(=O)c(=O)n(C)c2cc(S(=O)(=O)N3CCCC3C(=O)NCc3ccco3)ccc21
b: CCOP(=O)(CC(C(C)=O)C(O)c1ccccc1)OCC
c: O=C(COc1ccccc1)N/N=C/c1sc(=O)n(Cc2cccc(C(=O)O)c2)c1Cl
d: CC[C@H]1CN2CC[C@@]3(C(=O)Nc4ccccc43)[C@@H]2C[C@@H]1/C(=C\OC)C(=O)OC
Answer: d. CC[C@H]1CN2CC[C@@]3(C(=O)Nc4ccccc43)[C@@H]2C[C@@H]1/C(=C\OC)C(=O)OC
