Task: Answer the multiple-choice question.
Question: Which drug has a 11.586\% 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] O=c1c(Cl)c(Nc2cccc(Cl)c2)cnn1-c1nc2ccccc2s1
[b] COC(Cn1cc(C)c(=O)[nH]c1=O)OC
[c] Cc1cc(=O)[nH]c(N/N=C/c2ccc(O)c(O)c2)n1
[d] CCOC(=O)/C(=C\C=C\c1ccccc1)NC(=O)c1ccccc1
Answer: a. O=c1c(Cl)c(Nc2cccc(Cl)c2)cnn1-c1nc2ccccc2s1
