Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.656\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) CCOC(=O)C1CCN(C(=O)Cc2c(C(=O)O)n(C)c3ccccc23)CC1
b.) CCS(=O)(=O)N1CCC(c2nc(-c3ccc(C)cc3)no2)CC1
c.) CCOC(=O)C(Cc1c(F)cccc1Cl)c1ccnc2nc(N)nn12
Answer: b. CCS(=O)(=O)N1CCC(c2nc(-c3ccc(C)cc3)no2)CC1
