Task: Answer the multiple choice question.
Question: Which compound exhibits a 10.948\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=C(Nc1ccc(S(=O)(=O)Nc2ncccn2)cc1)c1ccc(Cl)c([N+](=O)[O-])c1
(b) Cc1ccc(CNc2nc(C)cs2)cc1
(c) CC(C)NC(=O)C12CC3CC(C1)CC(n1cnc(Cl)n1)(C3)C2
(d) CN1N=C(C(F)(F)F)CC1=O
Answer: a. O=C(Nc1ccc(S(=O)(=O)Nc2ncccn2)cc1)c1ccc(Cl)c([N+](=O)[O-])c1
