Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.733\% 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. CN(C)S(=O)(=O)c1cc(NC(=O)CN2CCN(c3ccccc3)CC2)ccc1Cl
b. CCOC(=O)N1CCC(NC(=O)c2cc(S(=O)(=O)N3CCOCC3)ccc2F)CC1
Answer: a. CN(C)S(=O)(=O)c1cc(NC(=O)CN2CCN(c3ccccc3)CC2)ccc1Cl
