Task: Answer the multiple choice question.
Query: Which compound exhibits a 7.784\% 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 other words.
Options:
a CNC(=O)C1C(=S)NC(N)=C(C#N)C1c1ccccc1
b CCOC(=O)C1=C(N)OC2=C(C(=O)CCC2)C1c1ccc2c(c1)OCO2
c COc1ccccc1CNC(=O)COC(=O)c1ccc(S(=O)(=O)N2CCCC2)cc1
d Cc1ccc(-c2cc(C(=O)NC3=NCCS3)c3ccccc3n2)cc1C
Answer: b. CCOC(=O)C1=C(N)OC2=C(C(=O)CCC2)C1c1ccc2c(c1)OCO2
