The formula for the limiting angle of resolution is:

θ = 1.22 × λ / (D × n)

where θ is the limiting angle of resolution in radians, λ is the wavelength of light, D is the diameter of the pupil, and n is the index of refraction of the eye.

Plugging in the given values, we get:

θ = 1.22 × 600 nm / (4.0 mm × 1.34) = 1.4 × 10^-4 rad

Therefore, the limiting angle of resolution for the eye is 1.4 × 10^-4 rad, which corresponds to choice C.
