All the options except 2 are true.

i.e Option 1,3,4 are true about Random Access Files.

Explanation:

Option 1 : In random access files we can access files randomly from anywhere using the memory address of that file. So, this option is absolutely true.
Option 2 : There is no need of data to be sorted. Because in random access we are accessing files with their addresses like an array so no need of data to be sorted.
Option 3 : As we are accessing data using memory addesses of the file so we can traverse the data in any format we want.
Option 4 : seekp is used to put the pointer to the specified memory address, and seekg is also used to put the pointer at the specified memory address but the difference it that seekp is used for output operation but seekg is used for input operaion. So, both are using to access files by a given position either for input or for output operation.

So, this was the solutions of the problem.

I hope I am able to solve your problem, if yes then do give it a like.

It really helps :)
