Shear stress varies linearly for both laminar and turbulent.
Wherelse velocity distribution laminar is parabolic, turbulent is logarithmic or sharp pointed.

In laminar flow, shear stress varies linearly with radial distance from the centre of the pipe. Still, in turbulent flow, the relationship is more complex and does not follow a simple linear variation.

B is also wrong. In turbulent flow, the velocity profile is constant outside the viscous sublayer, so shear stress variation should be 0.

Ideal fluid does not experience surface tension or experiences negligible surface tension. But, ideal fluid is irrotational, incompressible and non-viscous. So, there is no point of talking about Newton's law of viscosity.

Fluids that obey Newton's law of viscosity are known as Newtonian Fluids. For a Newtonian fluid, viscosity is entirely dependent upon the temperature and pressure of the fluid.
Examples: Water, air, emulsions.
