Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -1.020\% 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: C=CCNC(=O)c1ccc(Cl)cc1Cl
b: Cc1cc(C)n2nc(SCCOc3ccccc3)nc2n1
c: CC12COC3(C(N)=O)CC1CCC32C
d: CCC(C)[C@H](NC(=O)N1CC(=O)Nc2ccccc21)C(=O)N[C@H](Cc1ccccc1)C(=O)O
Answer: c. CC12COC3(C(N)=O)CC1CCC32C
