Two giant identical poles have been planted in the ground. One of the
poles was planted deeper than the other pole. The shadow of pole A is 10
meters long and the shadow of pole B is 8 meters long. How tall is pole
B?
(1) Pole A is hoisted 14 meters in the air.
(2) Pole B is located 2 meters from pole A

why is it A?

This question is bit unclear.

Using statement 1 we will be able to find the height of Pole A visible above the ground.

We cannot find anything about the pole inside the ground.

using statement 2: - is also of little help.

what is the source of this question?

I agree, the question is not clear enough, the question does not clearly say on which side of Pole A is Pole B.

"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 course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"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. They also have a very responsive team willing to help with any questions you might have."

"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."
