Task: Answer the multiple-choice question.
Query: Which compound exhibits a 5.669\% 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: CCNC(=O)NC(=O)c1csc([N+](=O)[O-])c1
b: COCCCN(C(=O)CCOc1ccccc1C)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
c: CSc1ccccc1OCc1cc(C(=O)N(C)Cc2cnccn2)no1
d: CC1CC(C)CN(C(=O)C(C)N(C)CC(=O)Nc2ccccc2Cl)C1
e: CCCC1CC(C)(C(=O)Cn2[nH]c(=O)ccc2=O)OC1=O
Answer: e. CCCC1CC(C)(C(=O)Cn2[nH]c(=O)ccc2=O)OC1=O
