Task: Answer the MCQ question.
Query: Which drug exhibits a -39.854% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(Nc1ccccc1)N1CCCN(c2ccc(C(F)(F)F)cc2[N+](=O)[O-])CC1
[b] O=C(Cc1ccc(F)cc1)Nc1c2c(nn1-c1cccc(Cl)c1)CS(=O)C2
Answer: a. O=C(Nc1ccccc1)N1CCCN(c2ccc(C(F)(F)F)cc2[N+](=O)[O-])CC1
