Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.886\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) Cc1cccn2cc(-c3cccc(S(=O)(=O)N4CCOCC4)c3)nc12
(b) COc1cccc(NC(=O)COC(=O)CC(NC(N)=O)c2ccc(Cl)cc2)c1
(c) CC1(c2nnc(Cc3ccccc3)o2)CC(c2ccccc2[N+](=O)[O-])=NO1
(d) O=C(c1ccc(Cl)cc1)N1CCC(=O)N(C(CO)Cc2ccccc2)CC1
Answer: c. CC1(c2nnc(Cc3ccccc3)o2)CC(c2ccccc2[N+](=O)[O-])=NO1
