In which type of staging, the specific impulse of all the individual stages are same?

In which type of staging, the specific impulse of all the individual stages are same? Correct Answer Restricted staging

In case of restricted staging, unlike optimal staging, all the the stages have the same value of specific impulse, structural ratio and payload ratio. One important aspect of restrcited staging is that total mass of initial stages is larger than the following upper stages.
