Solution

RAM is volatile and ROM is not is correct because volatile memory are memories which retains information when the power is on and the data vanishes immediately when the power goes off, that is similar to the actions of modern day RAM,But in ROM when power goes off it retains the data stored into it that is why ROM is non-volatile.
