Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.887\% 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 O=C(C1CCC1)N1CCN(S(=O)(=O)c2cccc(F)c2)CC1
b Cn1c(=O)c2[nH]c(-c3ccccc3)c(O)c2n(C)c1=O
Answer: a. O=C(C1CCC1)N1CCN(S(=O)(=O)c2cccc(F)c2)CC1
