Answer 1

None of the given options are correct.

Answer 2

The question is asking to identify the correct expression equivalent to $n^{4}-4$. We can solve this by expanding each of the given options and comparing them with the original expression.

1. $\{ (n-1)^{2}+1\} (n+1)^{2}+1\} $: This option expands to $n^4 + 2n^3 - 2n^ 2n - 3$, which is not equal to $n^4 - 4$.

2. $\{ (n-1)^{2}+1\} (n+1)^{2}-1\} $: This option expands to $n^4 + 2n^3 - 2n^2 - 2n + 3$, which is also not equal to $n^4 - 4$.

3. $\{ (n-1)^{2}-1\} (n+1)^{2}+1\} $: This option expands to $n^4 + 2n^3 - 2n^2 + 2n - 1$, which is not equal to $n^4 - 4$.

4. $\{ (n-1)^{2}+1\} (n-1)^{2}+1\} $: This option expands to $n^4 - 4n^2 + 4n - 3$, which is not equal to $n^4 - 4$.

None of the given options are equivalent to $n^{4}-4$. Therefore, the question seems to have a mistake as none of the provided options match the answer.
