Solution

Virtual memory uses secondary memory to increase the effective capacity of memory.

So, statement (a) is true.

In virtual memory, a program can be larger than the available main memory because secondary memory is used as backing storage.

So, statement (b) is also considered true in this context.

Program and data are stored in secondary memory, and required parts are brought into main memory during execution.

So, statement (c) is true.

Hence, none of the given statements is false.
