Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a -5.179\% 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: O=C(NC1CC1)C1=C[C@@H](c2coc3ccccc3c2=O)C[C@@H](OCc2ccc(CO)cc2)O1
b: Cc1ccc(N2CC(C(=O)N3CCC(C(=O)Nc4nnc(C(C)(C)C)s4)CC3)CC2=O)cc1
c: O=C(NCCc1ccccc1)/C(=C\c1cccc([N+](=O)[O-])c1)NC(=O)c1ccco1
d: O=S(=O)(c1ccc(NC(=S)N/N=C/c2ccc(Oc3ccccc3)cc2)cc1)N1CCOCC1
Answer: a. O=C(NC1CC1)C1=C[C@@H](c2coc3ccccc3c2=O)C[C@@H](OCc2ccc(CO)cc2)O1
