Keep a record of the random numbers that have already been picked, and if you pick a number that has already been picked pick another one until you get one that hasn't been picked. When you have your new unique number add it to the list of already picked numbers. That's probably the simplest way to do it, though probably not the most efficient.

When answering a question please:

Read the question carefully.
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.

Don't. Use one form, but randomise the data you load into it - don't try to create a new form for each question!

Then it's pretty simple: create a set of questions, with the answer (or answers) and keep a record in your app of which questions you have already asked. That's not difficult - the simplest way is to create a text file which has a line per question, with questions and answers separated by '|' characters:

question|CorrectAnswerNumber|Answer1|Answer2|Answer3
question|CorrectAnswerNumber|Answer1|Answer2|Answer3
question|CorrectAnswerNumber|Answer1|Answer2|Answer3
...

You can then read them all into an Array of String using File.ReadAllLines, and separate each line into questions and answers using string.Split.
Keep a separate collection of question numbers you have asked, and you can select a question at random from the array of strings. Split that line, and fill in the fields on the current form.

But... this is your homework, so I'll give you no code!
It's pretty simple if you think about it for a bit and try a few experiments.
