Task: Answer the multiple choice question.
Query: Which compound has a 1.266\% 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 other words.
Options:
a.) COC(=O)c1cc(NC(=O)CN2CCC(C(N)=O)(N3CCCCC3)CC2)cc(C(=O)OC)c1
b.) O=C(CSc1nc(-c2ccccc2)c(-c2ccccc2)o1)Nc1nnc(-c2ccccc2)s1
c.) Cc1ccc(NC(=O)CN(C)CC(=O)Nc2cccc(F)c2)cc1[N+](=O)[O-]
d.) COCCN1C(=O)C(=O)/C(=C(/O)c2ccc(S(=O)(=O)N3CCCCC3)cc2)C1c1ccc(OC)c(OC)c1
Answer: c. Cc1ccc(NC(=O)CN(C)CC(=O)Nc2cccc(F)c2)cc1[N+](=O)[O-]
