Task: Answer the multiple-choice question.
Query: Which drug exhibits a -3.305\% 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) Cn1c(CCC(=O)OCC(=O)NCc2ccccc2Cl)nc(=O)c2ccccc21
b) CC(C)(C)OC(=O)N1CCC[C@H]1c1nnc(SCc2ccc(Cl)cc2Cl)o1
c) CCN(CC)CCCNC(=O)c1nn(-c2cc(OC)cc(OC)c2)c(=O)c2ccccc12
d) CCCC1=C(C(=O)OCC)C(c2c(C)nn(-c3ccccc3)c2Cl)C(C#N)=C(N)O1
Answer: d. CCCC1=C(C(=O)OCC)C(c2c(C)nn(-c3ccccc3)c2Cl)C(C#N)=C(N)O1
