Task: Answer the multiple choice question.
Query: Which compound exhibits a 6.939\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: Cc1nnc(N/N=C/c2c(O)n(-c3cccc(C(F)(F)F)c3)c(=O)c3ccccc23)[nH]c1=O
b: Cn1cnnc1SCc1nnc(-c2ccccc2Br)o1
Answer: a. Cc1nnc(N/N=C/c2c(O)n(-c3cccc(C(F)(F)F)c3)c(=O)c3ccccc23)[nH]c1=O
