Task: Answer the MCQ question.
Query: Which drug has a 9.512\% 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: C(=N/Nc1nc2ccccc2[nH]1)\c1ccc2c(c1)OCCO2
b: C/C(CC(=O)NCc1ccco1)=N\NC(=O)Cc1ccc(-c2ccccc2)cc1
c: COc1ccc(C(C)=O)cc1COc1cc(C)c(Cl)c(C)c1
d: O=C(NNc1c2ccccc2nc2ccccc12)C(O)c1ccccc1
Answer: d. O=C(NNc1c2ccccc2nc2ccccc12)C(O)c1ccccc1
