Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 1.346\% 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 additional words.
Options:
[a] CCOC(=O)c1ccc2c(c1)n(CCO)c(C)[n+]2CC.[I-]
[b] O=C(Nc1ccccc1Oc1ccccc1)c1ccccc1F
[c] CC1=C(C(N)=O)C(c2ccccc2)n2nc(-c3cccs3)nc2N1
[d] CCOc1ccc(CCNC(=O)COC(=O)Cn2cnc3ccccc3c2=O)cc1OCC
[e] O=C(C1CCCCC1)N1CCC(c2nc3ccccc3[nH]2)CC1
Answer: c. CC1=C(C(N)=O)C(c2ccccc2)n2nc(-c3cccs3)nc2N1
