Which one of the following options is CORRECT?
A
P→ Ideal Fluid; Q→ Ideal Bingham plastic
R→ Non-Newtonian fluid; S→ Newtonian fluid
B
P→ Real solid; Q → Ideal Bingham plastic
S→ Newtonian fluid; T→ Ideal Fluid
C
P→ Ideal Fluid; Q→ Ideal Bingham plastic
R→ Non-Newtonian fluid; T→ Real solid
D
P→ Real solid; Q → Newtonian fluid
