Task: Answer the multiple-choice question.
Question: Which drug has a 24.110\% 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(=O)OC(C)[C@H]1CC[C@H]2[C@@H]3CC[C@H]4C[C@@H](OC(C)=O)CC[C@]4(C)C3=CC[C@]12C
b: CCNS(=O)(=O)c1ccc(CCC(=O)N2CCOCC2)cc1
c: CCO[C@H]1OC(C(N)=O)=C[C@@H](C2CCCCC2)[C@@H]1CCCO
d: O=C(CN1C(=O)CSc2ccc(S(=O)(=O)N3CCOCC3)cc21)NCc1ccc(F)cc1
Answer: b. CCNS(=O)(=O)c1ccc(CCC(=O)N2CCOCC2)cc1
