If a compressed spring is dissolved in acid, what happens to the elastic potential energy of the spring ?

If the potential energy of a spring is V on stretching it by 2cm , then its potential energy when it is stretched by 10cm will be

If the potential energy of a spring is V on stretching it by 2 cm , then its potential energy when it is stretched by 10 cm will be

If the potential energy of a spring is V on stretching it by 2cm , then its potential energy when it is stretched by 10cm will be

Potential energy of an ideal spring, when stretched by 1 cm is U. Spring is now cut in two equal parts and connected in parallel. If the new combination of spring is compressed by 2 cm, then potential energy stored is
