Task: Answer the multiple choice question.
Query: Which drug has a 12.288% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. C/C(=N\Nc1cc(N2CCOCC2)nc(C)n1)c1cccc([N+](=O)[O-])c1
b. O=C(COC(=O)CSc1ccc([N+](=O)[O-])cc1)NCC1CCCO1
c. COc1ccc(C2CC(=O)n3nc(C45CC6CC(CC(C6)C4)C5)nc3S2)cc1OC
d. Cc1cccc(/C=N/c2sc3c(c2C(=O)OC(C)(C)C)CCN(C)C3)c1O
e. O=C1CC(c2cccc(Cl)c2)Cc2nc(N3CCOCC3)ncc21
Answer: b. O=C(COC(=O)CSc1ccc([N+](=O)[O-])cc1)NCC1CCCO1
