I'm obligated to ask this question of Terzaghi’s Analysis topic in chapter Bearing Capacity of Geotechnical Engineering II

Answer 1

The correct answer is (a) φ changes when the soil is compressed and strip footing has a rough base

Easy explanation: As the soil compress, φ changes; slight downward movement of footing may not develop fully the plastic planes.
