Solution

The correct option is C equal to the original length
The ratio of stress to strain is known as the elastic modulus of the material.
Elastic Modulus, $E = \frac{s t r e s s}{s t r a i n}$
When the change in elongation to the original length is minimal, then the modulus of elasticity is dimensionally equivalent to the stress.
