Vibing cat - quant problem solving

GRE Quant Problem Solving
1

I have been working on factors-multiples problems and got a bit stuck at this question and had a difficult time getting the correct answer. can someone explain the process to me? the original answer i got was b (when its actually c). thank you!

A vibing cat (watch video first) takes 6 seconds to complete a quarter-turn (state B), comes back to its original location (state A) at the same speed, and then continues the process indefinitely. At this rate, what would be the state of the cat after 2 minutes and 30 seconds?
a. cat will be at state a
b. cat will be moving from state a to state b
c. cat will be at state b
d. cat will be moving from state b to state a
e. cannot be determined

I feel the question should state what is the starting point of the cat, if it’s A then the solution makes sense. Also, the last option is relevant in this case.

If “original location” indicates the initial position then it makes sense

I thought the video made that clear; is that not the case?
