Problem statement: Answer the multiple choice question.
Query: Which drug has a 1.400\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CCOC(=O)N1CCC(N2CCN(C3CCCC3)C(CCO)C2)CC1
[b] CCNC(=O)/C(C#N)=C/c1c(N2CCN(c3ccccc3)CC2)nc2ccccn2c1=O
[c] CCOC(=O)CS(=O)(=O)c1ccc(O)cc1
Answer: a. CCOC(=O)N1CCC(N2CCN(C3CCCC3)C(CCO)C2)CC1
