Always remember that the clause that precedes the colon mark should be an independent clause. It should contain both a subject and a predicate. In other words, you should not use a colon in situations like below:
a. The books you will need include: Treasure Island and The Swiss Family Robinson. (should have no colon after include)
 
The same thing with letters B and D.
