Task: Answer the MCQ question.
Question: Which compound has a 13.554\% 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 or b without using any other words.
Options:
[a] O=C1C(Cc2ccccc2)S/C(=N/N=C/c2ccco2)N1c1ccccc1
[b] CC1(C)CC(=O)C(C2C3=C(CC(C)(C)CC3=O)Oc3ccccc32)=C(O)C1
Answer: a. O=C1C(Cc2ccccc2)S/C(=N/N=C/c2ccco2)N1c1ccccc1
