Task: Answer the multiple-choice question.
Question: Which compound exhibits a -0.497\% 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. O=C1NC2=C(C(=O)CCC2)C(c2ccc3ncccc3c2)N1
b. CC(C)c1ccc(CNC(=O)C(=O)NCC2CCCO2)cc1
c. CCOC(=O)c1ccc(NCC(O)COc2ccccc2)cc1
d. O=C1C2C3C=CC(C2C(=O)N1C1CCCCC1)C1C2C(=O)N(C4CCCCC4)C(=O)C2C31
Answer: a. O=C1NC2=C(C(=O)CCC2)C(c2ccc3ncccc3c2)N1
