Task: Answer the multiple choice question.
Question: Which compound has a 0.174\% 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: O=C(Nc1cc(=O)[nH]c(=O)[nH]1)c1cccc(Br)c1
b: CC(C)CCN(C(=O)CCCSc1nc2ccccc2[nH]1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
c: COc1ccc(S(=O)(=O)N2CCCCC2)cc1NC(=O)Cn1c(=O)cnc2ccccc21
d: CCOc1ccc(N(C(C)C(=O)N2CCCCCC2)S(C)(=O)=O)cc1
Answer: d. CCOc1ccc(N(C(C)C(=O)N2CCCCCC2)S(C)(=O)=O)cc1
