Task: Answer the multiple-choice question.
Query: Which drug exhibits a 10.780\% 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) O=C(NC1CCCCC1)c1ccccc1-c1ccccc1
(b) C=C(C)C1CC=C(CN2CC(C)OC(C)C2)CC1
(c) C/C(=N\NC(=O)CSCc1ccccc1Cl)c1cccc(NC(=O)c2ccccc2)c1
(d) O=C(Nc1ncccn1)c1ccc([N+](=O)[O-])o1
(e) COc1cccc(CC(=O)OCC(=O)NC2CCCC2)c1
Answer: d. O=C(Nc1ncccn1)c1ccc([N+](=O)[O-])o1
