Can you choose any one? Can I trust intuition? Do you want a quick answer or a slow answer?

It reminds me of 

A bat and a ball together cost $1.10. The bat costs one dollar more than the ball. How much does the ball cost?

Approach your problem from the right end and begin with the answers. Then one day, perhaps you will find the final question..

number of elements in each figure (tri + quad):

4 5 5
7 8 8
4 5 x
x should be 5 so choose between b & d. Then maybe d as on every line, there are only 2 vertices at the centre.

c because it best shows the end result of a process of rotating, shifting, and reflecting the original lines.

Looks like 1 transformation of each type is "allowed" and the reflection seems to take place across the longest straight line in each example.

Have to look at it some more though.

Robert Harbin’s “Origami Book 3,” p. 25 “Crouching Samurai.”

And it’s e. The fold which creates the sword of the Samurai.

This is the Brainteaser forum and has its own etiquette.

But I will point the typos out to you.  

waist - you mean waste time.  But that is ok.

Ah the second typo has been corrected.  Very good.

But I still have to go to a Math class now. :)

 that is why one need the sword of the Samurai, to cut off the typos! It was a double puzzle ? an answer within the answer?

Add the funny little picture of Einstein and it is really a multi-dimensional puzzle!

One way to help solve the line drawing puzzle is to reconstruct each drawing using colored pencils - a different color for each continuous line.

Then see how you can work with those lines - rotate, mirror-reflect, shift, to form the next image in the sequence.

At least this is how I think about it. 

Could be completely wrong and the real answer is waiting on a different plane...

**

and yes, typos can be like "Freudian slips"- funny little verbal mistakes that reveal more than what one had intended.

Can be very entertaining though, in any language.
