Problem statement: Answer the multiple choice question.
Question: Which drug has a 2.020\% 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 additional words.
Options:
[a] CCOC(=O)C1CCN(c2c(NCCCN3CCCCC3)c(=O)c2=O)CC1
[b] Cc1ccc(NC(=O)CSc2nc(O)c(Cc3ccccc3)c(=O)n2-c2ccccc2)cc1
[c] CCOC(=O)c1c(NC(=O)CSc2nnc(C)c(=O)[nH]2)sc2c1CCC2
[d] COc1cccc(CC(NC(C)=O)C(=O)NC2CCN(S(=O)(=O)c3cccc4ccccc34)CC2)c1
Answer: c. CCOC(=O)c1c(NC(=O)CSc2nnc(C)c(=O)[nH]2)sc2c1CCC2
