Step-by-step explanation:

Correct option is

А π/4

с 3л/4

The diagonals are given by AB — BC = 4i — -

2j + 4k, AB + BC = 2i − 2j These vectors have magnitudes 6 and 2√2 respectively, and their dot product is 12. Therefore the angle between them is COS -1 12 (6) (2√2) = cos -1 1 √2 or minus this value i.e.3/4 4
