Task: Answer the multiple-choice question.
Query: Which drug has a 5.480\% 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] NC(=O)C1(N2CCCCC2)CCN(C(=S)NCCc2ccccc2)CC1
[b] Cc1ccc(CNC(=O)C2(NC(=O)Nc3ccc(C)cc3)CCCCC2)cc1
[c] O=C(O)C1CCCCC1C(=O)Nc1cccc(Br)c1
[d] CCOC(=O)C1=C(N)Oc2c(oc(CO)cc2=O)C1c1ccc(Cl)cc1
[e] CCC1=Nc2ccccc2-c2nnc(SC)nc2O1
Answer: d. CCOC(=O)C1=C(N)Oc2c(oc(CO)cc2=O)C1c1ccc(Cl)cc1
