Task: Answer the multiple-choice question.
Question: Which compound exhibits a 17.930\% 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 additional words.
Options:
a: CSc1ccc(-c2nc(CSCC(=O)N3CCOCC3)c(C)o2)cc1
b: CCOC(=O)CCc1c(C)c2ccc(OC3CCCCC3=O)cc2oc1=O
c: Cc1cc(C)n(C(N)=NC(=O)c2ccc([N+](=O)[O-])cc2)n1
d: Cc1ccc(C)c(Cn2nnc3c(=O)[nH]c(C4CCCN(C(=O)c5cccs5)C4)nc32)c1
e: O=C(c1cc(-c2cccc(Cl)c2)on1)N1CCN(c2ccc(F)cc2)CC1
Answer: b. CCOC(=O)CCc1c(C)c2ccc(OC3CCCCC3=O)cc2oc1=O
