Question

How can you reduce the number of calls when using a breakpoint on the ReadFile API?

a.

By only breaking when the specific handle to the Cryptex archive is specified.

b.

By restricting the breakpoint to calls made on the system.

c.

By only breaking when the specific handle to the archive file is specified.

d.

By only breaking when the specific handle to the Cryptex executable is specified.
