Task: Answer the MCQ question.
Question: Which drug has a 0.993\% 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.) COC(=O)C1C(=O)C2=C(CC1C)NC(C)=C(C(=O)OCc1ccc(OC)cc1)C2c1ccc(C)o1
b.) O=C(Nc1ccc2c(c1)OCO2)OCc1ccccc1
c.) COC(=O)C1=C(O)/C(=C/c2cccc(OC)c2O)N=C1C
d.) O=C(Nc1ccc(Cl)c([N+](=O)[O-])c1)c1ccc2c(c1)OCCO2
Answer: d. O=C(Nc1ccc(Cl)c([N+](=O)[O-])c1)c1ccc2c(c1)OCCO2
