Task: Answer the multiple-choice question.
Question: Which compound has a 6.865\% 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.) COC(=O)C1C(=O)C2=C(CC1C)NC(C)=C(C(=O)OC1CCCC1)C2c1ccc(N(C)C)cc1
b.) O=S(=O)(/N=C(/Nc1ccccc1F)c1ccccc1)c1ccccc1
c.) O=C(Nc1ccc(N2CCCCC2)c(Cl)c1)c1ncn[nH]1
d.) N#Cc1c(N)[nH]c(=S)c(C#N)c1-c1ccccc1
e.) O=C(N[C@H]1CCC(=O)N([C@H](CSc2ccccc2)Cc2ccccc2)CC1)OCc1ccccc1
Answer: a. COC(=O)C1C(=O)C2=C(CC1C)NC(C)=C(C(=O)OC1CCCC1)C2c1ccc(N(C)C)cc1
