Answer: Pressure is defined as the force acting per unit area.
P =

\frac{Force}{Area}

Lesser the area, greater the pressure.
Area in I case =

60 \times 40 = 2400 c m^{2}

Area in II case =

40 \times 20 = 800 c m^{2}

Area in III case =

60 \times 20 = 1200 c m^{2}

Area will be minimum when breadth and width form the base.
Hence, the correct answer is option B.
