Task: Answer the multiple-choice question.
Question: Which drug has a -0.956\% 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 Cc1cc(C(=O)CC#N)c(C)n1CC(F)(F)F
b O=C(N/N=C\c1ccco1)Nc1cccc(Cl)c1
Answer: a. Cc1cc(C(=O)CC#N)c(C)n1CC(F)(F)F
