Task: Answer the multiple choice question.
Query: Which compound exhibits a 10.974\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:

(b) CCOC(=O)c1c(C)noc1-c1ccco1
(c) Cc1ccc(C(=O)NCc2ccc(F)cc2)cc1NC1=NC2CS(=O)(=O)CC2S1
(d) COc1ccccc1NS(=O)(=O)c1cc(NC(=O)c2ccc(C)o2)ccc1N1CCCC1
(e) COc1ccc(C(=O)OCCN2CCN(C3=NS(=O)(=O)c4ccccc43)CC2)cc1OC
Answer: a. O=[N+]([O-])c1cc(Cl)cc(/C=N\Nc2ccccn2)c1O
