Task: Answer the multiple-choice question.
Question: Which compound has a 2.546\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a NC(N)=N/N=C/c1ccc(OCc2ccccc2)c(OCc2ccccc2)c1
b COc1ccc(Cl)cc1NC(=S)N(Cc1ccccc1C)CC1CCC(C(=O)O)CC1
c CCC(C)[C@H](NC(=O)N1CC(=O)Nc2ccccc21)C(=O)Nc1nccs1
Answer: a. NC(N)=N/N=C/c1ccc(OCc2ccccc2)c(OCc2ccccc2)c1
