  4. A CD-R is a writable compact disc onto which a user can permanently burn digital data one time; a CD-RW is a rewritable compact disc onto which a user can burn digital data repeatedly or replace data previously stored on the disc.
Explanation
Answer: D - A CD-R is a writable compact disc onto which a user can burn digital data one time. Writing material to a CD-R is a one-time event - it cannot be erased or overwritten at a later date. A CD-RW is a rewritable compact disc onto which a user can burn digital data repeatedly or replace data previously stored on the disc. CD-RWs do have more space than CD-Rs, but there are other differences between them, as well.
