Task: Answer the multiple choice question.
Question: Which drug has a 16.564\% 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=C(O)c1c(Cl)cccc1Cl
b COCCCNC(=O)COc1cc(C)c(Cl)c(C)c1
c CCCCC(=O)OCC(=O)c1ccc(OCC)cc1
d O=C(CN1CCN(c2ccc(F)cc2)CC1)N1N=CCC1c1ccccc1
e CCCCn1c(-c2ccccc2)nnc1-c1ccccc1
Answer: a. O=C(O)c1c(Cl)cccc1Cl
