Problem statement: Answer the multiple choice question.
Query: Which drug has a 4.418\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. Cc1cc(C)c(C#N)c(SCc2c(F)cccc2[N+](=O)[O-])n1
b. O=C(CSc1nnc(CNC(=O)c2c(F)cccc2F)o1)c1ccccc1
Answer: a. Cc1cc(C)c(C#N)c(SCc2c(F)cccc2[N+](=O)[O-])n1
