Task: Answer the multiple-choice question.
Question: Which drug has a 4.790\% 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] NS(=O)(=O)c1ccc(CCNC(=O)c2ccccc2F)cc1
[b] O=[N+]([O-])c1ccc(Oc2ccc(S(=O)(=O)Nc3ccccc3)cc2)cc1
[c] CCN(CC)CCCN1CC(=O)N2[C@@H](Cc3c([nH]c4ccccc34)C2(C)C)C1=O
Answer: a. NS(=O)(=O)c1ccc(CCNC(=O)c2ccccc2F)cc1
