(i) Order = 1, Degree = 1

[Here, we have (dy/dx)']

(ii) Order = 1, Degree = 1

[We have (dy/dx)']

(iii) We have (d²y/dx²)'; So, order = 2; Degree = 1 

(iv) Squaring both sides, [(d²y/dx²) + x]² = y + (dy/dx) 

We have (d²y/dx²)² 

∴ Order = 2 

Degree = 2

(v) Squaring both sides, we get 

((d²y/dx²) - y)² = ((dy/dx) + (d³y/dx³))³ = 0

We have (d³y/dx³)³ 

Order = 3; Degree = 3

The correct answer is C) Night blindness.
