Task: Answer the multiple choice question.
Question: Which drug has a -5.145\% 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 COc1ccc(-n2nc3ccccc3n2)cc1
b COc1ccc(C(=O)COC(=O)c2ccc3ccccc3n2)cc1
c O=C(CC12CC3CC(CC(C3)C1)C2)NC(=S)Nc1ccc(CN2CCOCC2)cc1
d CC(/C=C\C=C\c1ccccc1)=N\NC(=O)c1cncc(Br)c1
Answer: a. COc1ccc(-n2nc3ccccc3n2)cc1
