Task: Answer the MCQ question.
Query: Which compound exhibits a 4.689\% 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, d, or e without using any other words.
Options:
a) CCOC(=O)/C(C#N)=C/Nc1ccccc1OC(F)(F)F
b) COc1cc(/C=C/C(=O)O)ccc1S(=O)(=O)N1CCCc2ccccc21
c) CC(C)(C)Nc1scc(-c2ccccc2)[n+]1-c1ccccc1.[Br-]
d) COC(=O)c1ccc2c(c1)NC(=O)C(N(CC(C)C)CC(C)C)S2
e) CCOC(=O)c1c(C)nc2sc3c(=O)[nH]cnc3c2c1-c1ccc(OC)cc1
Answer: a. CCOC(=O)/C(C#N)=C/Nc1ccccc1OC(F)(F)F
