save_npz saves sparse matrices in a compressed NumPy archive format called NPZ.Step 2: Understand NPZ format
NPZ files are zipped archives containing multiple NumPy arrays, ideal for sparse matrix data.Final Answer:
NPZ (NumPy compressed archive) -> Option BQuick Check:
save_npz format = NPZ [OK]
Quick Trick: save_npz uses NPZ format, not CSV or JSON [OK]
