I'm feeling lucky with Option C. Compiler errors are like my middle name!

Option A is the way to go. Who doesn't love a good ol' private constructor? It's a classic!

This is a real head-scratcher. I'm going to have to go with Option D. Gotta love those compiler errors!

I disagree, I believe the correct answer is Option C because it uses a private static inner class.

Ah, tricky question. I'm going with Option B. The private constructor should do the trick.

Option C looks good to me. It allows the first instantiation to succeed and causes a compilation error on the second one.
