Task: Answer the multiple-choice question.
Question: Which drug exhibits a 10.011\% 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] CC(Oc1cccc(Cl)c1)C(=O)Nc1ccc(S(=O)(=O)Nc2ncccn2)cc1
[b] O=C(NC(=Nc1ccccc1)N1CCOCC1)Nc1ccccc1
[c] CCN(CCO)C(=O)C12CCC(C)(C(=O)C1)C2(C)C
[d] CCc1nnc(NC2=NCCC2)s1
Answer: b. O=C(NC(=Nc1ccccc1)N1CCOCC1)Nc1ccccc1
