Task: Answer the multiple-choice question.
Question: Which drug exhibits a 13.214\% 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.) CCOC(=O)CC(/C(C)=N\O)c1ccccc1
b.) O=C(Nc1ccc2ccccc2c1)c1ccc(Cl)cc1
c.) Cc1cc(NC(=O)CSC2=Nc3ccccc3C3=NC(Cc4ccccc4)C(=O)N23)n[nH]1
d.) OCC1OC(n2cnc3c(NC4CCCC4)ncnc32)C(O)C1O
Answer: b. O=C(Nc1ccc2ccccc2c1)c1ccc(Cl)cc1
