Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 15.362\% 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 or b without using any other words.
Options:
a) Cc1ccc(C(=O)Nn2c(N)c(S(=O)(=O)c3ccc(C)cc3)c3nc4ccccc4nc32)cc1
b) CC(=O)c1cc(C#N)c(N2CCCC2)nc1C
Answer: b. CC(=O)c1cc(C#N)c(N2CCCC2)nc1C
