Problem statement: Answer the multiple choice question.
Query: Which drug has a 4.886\% 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] CCOC(=O)CSc1nnc(CNC(=O)c2ccc(S(=O)(=O)N3CCCC3)cc2)n1C
[b] Cc1c(C)c2c(OCC(=O)N[C@@H](Cc3ccccc3)C(=O)O)cc3c(c2oc1=O)CCC(C)(C)O3
[c] O=C1c2cccnc2C(=O)N1Cc1ccccc1
[d] C=CCSc1nnc(C)n1-c1ccc(Cl)cc1
Answer: c. O=C1c2cccnc2C(=O)N1Cc1ccccc1
