Task: Answer the multiple choice question.
Question: Which drug has a 14.167\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCN(CC)C(=O)c1ccc(-c2nnc(Nc3cccc(O)c3)c3ccccc23)cc1
b: O=C(COc1ncnc2ccccc12)Nc1ccc(S(=O)(=O)N2CCOCC2)cc1
c: O=[N+]([O-])c1ccc(N2CCCCCC2)c2ncccc12
d: Cc1ccnc(NC(=O)C2CCN(S(=O)(=O)c3ccc4ccccc4c3)CC2)c1
Answer: a. CCN(CC)C(=O)c1ccc(-c2nnc(Nc3cccc(O)c3)c3ccccc23)cc1
