Task: Answer the multiple choice question.
Question: Which compound has a 0.720\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: Cc1cccc(-c2nc(C)cc(=O)[nH]2)c1
b: COC(=O)CSc1nc(NCC(C)C)nc(N2CCOCC2)n1
c: CS(=O)(=O)N1CCN(C(=O)C2c3ccccc3Oc3ccccc32)CC1
d: O=C(NN1CCOCC1)c1sc2cccc(F)c2c1Cl
e: CCOC(=O)/C=C/C(=O)Nc1ccc(S(=O)(=O)N2CCc3ccccc32)cc1
Answer: b. COC(=O)CSc1nc(NCC(C)C)nc(N2CCOCC2)n1
