Task: Answer the MCQ question.
Question: Which drug exhibits a 7.954\% 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: CCN(CC)CCN=Cc1c(O)n(CCc2ccccc2)c(=O)[nH]c1=O
b: CC(=O)Nc1c(C(N)=O)oc2ccc(Cl)cc12
c: CCCN(CCC)S(=O)(=O)c1cccc(C(=O)Nc2ccc3c(c2)OCO3)c1
Answer: b. CC(=O)Nc1c(C(N)=O)oc2ccc(Cl)cc12
