Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.869\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C(c1ccco1)N1N=C(c2cccs2)CC1c1cc([N+](=O)[O-])ccc1O
b: O=C(Nc1ccccn1)c1ccc(S(=O)(=O)N2CCCCC2)cc1
c: c1ccc(-c2csc(NC3=NCCCCC3)n2)cc1
Answer: a. O=C(c1ccco1)N1N=C(c2cccs2)CC1c1cc([N+](=O)[O-])ccc1O
