If the length of the subnormal at any point of the curve is constant, then the eccentricity of this curve is

View answer and explanation

Correct option: D

\mathrm{e}=1

Option D (e=1) is correct because the condition of constant subnormal implies the curve is a parabola, which has an eccentricity of 1.
