Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -0.491\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CCSc1nc2c(c(=O)[nH]1)C(c1cccnc1)C(C(=O)OC)=C(C)N2
[b] O=C(Nn1cnnc1)c1ccc(OC(F)(F)C(F)C(F)(F)F)cc1
Answer: a. CCSc1nc2c(c(=O)[nH]1)C(c1cccnc1)C(C(=O)OC)=C(C)N2
