Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -0.704% 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 additional words.
Options:
a) O=c1c2c(nc3n1CCCCC3)sc1c(O)cccc12
b) CCc1nc(N2CCN(C(C)=O)CC2)c(C#N)c2c1COC(C)(C)C2
Answer: b. CCc1nc(N2CCN(C(C)=O)CC2)c(C#N)c2c1COC(C)(C)C2
