Task: Answer the multiple choice question.
Query: Which compound has a 12.426\% 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:
a O=S1(=O)Cc2cc3ccccc3cc2C1
b CN(CC1CCCO1)S(=O)(=O)c1ccc(C(=O)Nc2ccc3c(c2)OCO3)cc1
c C/C(N)=C(/C#N)C(=O)COC(=O)c1ccccc1O
d Cc1ccc(CN2C(=O)CCSc3ccc(Cl)cc32)cc1
e CN(C)CCc1c[nH]c2ccc(Cn3cncn3)cc12.O=C(O)c1ccccc1
Answer: a. O=S1(=O)Cc2cc3ccccc3cc2C1
