Task: Answer the multiple choice question.
Question: Which compound exhibits a -0.048\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a.) CC(C)(C)c1cc(NC(=O)c2cccs2)no1
b.) O=S(=O)(c1ccc(OC(F)(F)F)cc1)N1CCCC(N2CCOCC2)C1
c.) CC(Nc1nc(Cl)ccc1[N+](=O)[O-])C(=O)O
d.) CC(=O)c1ccc(NS(=O)(=O)c2ccc(C(C)(C)C)cc2)cc1
e.) Clc1ccc(C2[C@H]3CN(Cc4cccnc4)[C@H](c4ccccc4)C34CC2(c2ccccc2)C4)cn1
Answer: c. CC(Nc1nc(Cl)ccc1[N+](=O)[O-])C(=O)O
