Good question, I would love to know how the OA is 60

Shortest distance between 2 points is a straight line, and the shortest distance between (0,0) to a point on this line should be between (0,0) and (0,-100), distance thus being 100.

There must be something missing from the question - (E) is definitely the correct answer to the question as written.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information.

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score.

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
