A) 1.42 μm
B) 2.01 μm
C) 3.12 μm
D) 4.12 μm
E) 5.44 μm

The slit spacing (d) can be found using the formula for diffraction maxima: d * sin(θ) = m * λ, where m is the order of the maximum (m=1 for first order), λ is the wavelength (600 nm = 600 x 10^-9 m), and θ is the angle (25.0°). Solving for d gives approximately 1.42 μm.
