A causal language model uses a sparse attention mechanism. When calculating the output for the token at position i=10, the set of indices for the key-value pairs to be attended to is specified as G = {2, 5, 9}. Which of the following statements accurately describes the computation for the token at position 10?

A causal language model is using a sparse attention mechanism to compute the output for the token at position i = 8. The set G defines the indices of the key-value pairs that the current token will attend to. Which of the following options represents an invalid set G for this computation?
