Task: Answer the multiple choice question.
Query: Which drug has a 6.693\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a O=C(CSc1nnc(-c2n[nH]c3ccccc23)n1-c1ccccc1)Nc1ccccc1Cl
b COc1ccc(-c2cc(C(=O)Nc3ccccc3SC)no2)cc1
c COc1ccc([N+](=O)[O-])cc1NC(=O)Cn1ccc(C(F)(F)F)n1
Answer: a. O=C(CSc1nnc(-c2n[nH]c3ccccc23)n1-c1ccccc1)Nc1ccccc1Cl
