Task: Answer the MCQ question.
Question: Which drug exhibits a -17.326% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CCCn1c(C)cc(C(=O)COC(=O)c2c(C)nn(-c3ccccc3)c2C)c1C
b CNCCCN1c2ccccc2CCc2ccccc21.Cl
c C/C(CC(=O)Nc1cc(C)ccn1)=N\NC(=O)C(=O)Nc1cccc(C)c1
d O=C(OCc1nc2ccccc2s1)c1cnccn1
Answer: d. O=C(OCc1nc2ccccc2s1)c1cnccn1
