Answer & Solution

Correct Answer

(A) \(7\)

Step-by-step Solution

Detailed explanation

\(|\mathrm{A}|=2 \) \(\underbrace{\operatorname{adj}(\operatorname{adj}(\operatorname{adj} \ldots . .(\mathrm{a})))}_{2024 \text { times }}=|\mathrm{A}|^{(\mathrm{n}-1)^{2024}} \) \( \quad=|\mathrm{A}|^{2024} \) \( =2^{2^{2024}}\)…
