Task: Answer the multiple choice question.
Query: Which compound exhibits a 5.650\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CN1CCN(c2nc(-c3ccccc3)ncc2S(C)(=O)=O)CC1
b: CCN(CC)C(=O)C(=O)Nc1ccc(Oc2ccccc2)cc1
c: Cc1ccc(NC(=O)CCN2C(=O)c3ccccc3S2(=O)=O)cc1C
d: C/C(=N\NC(=O)CSc1nc2ccccc2s1)c1ccco1
Answer: b. CCN(CC)C(=O)C(=O)Nc1ccc(Oc2ccccc2)cc1
