Task: Answer the multiple choice question.
Query: Which compound exhibits a 0.757\% 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) CCOC1=CC(=O)N(Cc2ccccc2)C1
b) CCC1=NC(c2ccc(OC)cc2OC)N(O)C1(C)C
c) Cl.O=c1[nH]cnc2c1N1CCC2CC1
d) COc1ccc(CCNC(=O)CSC2=Nc3ccccc3C3=NC(C(C)C)C(=O)N23)cc1OC
e) COc1ccc(NC(=O)/C(N=Nc2cc(S(=O)(=O)Nc3ccc(OC)cc3)ccc2OC)=C(\C)O)cc1
Answer: b. CCC1=NC(c2ccc(OC)cc2OC)N(O)C1(C)C
