The human cortex is approximately 2.5mm thick and has a surface area of about 1000cm2. Option B is incorrect because the surface area is in mm2, not cm2. Option C is incorrect because a surface area of 1m2 is much larger than the human cortex. Option D has the correct thickness but the surface area is too small, as it is given in cm2.
