Task: Answer the MCQ question.
Question: Which drug exhibits a 0.759\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a CCOC(=O)c1sc2nc(C)c([N+](=O)[O-])c(COC)c2c1N
b O=C(CCc1nnc(-c2ccsc2)o1)N1CCc2c(Cl)cccc2C1
c COc1ccc2c(c1)C(c1cccs1)=NNC(c1cccnc1)=N2
Answer: b. O=C(CCc1nnc(-c2ccsc2)o1)N1CCc2c(Cl)cccc2C1
