So im practicing command of evidence questions using whiz and the answer key says its A which I got correct but then when I gave the question to chatgpt and I explained by reasoning it said C was still correct so I searched up the question on google and it says C is correct so im confused am I right or wrong A seems more correct because it directly supports it by saying to be able to understand the timelines and scales of the eruptions you have to be able to identify and match them and in A the first part of the sentence is the identify part and the last part is the timeline part

Hi, Im a sophomore right now school ended so I'm currently studying for psat nmsqt junior year and these were my first test scores. I don't know if these are good or not but I sort of need like a study plan for reading and writing, I already have down what I need to study for math. I didn't want to waste an actual practice test so I took the 8/9 one instead. Please give me suggestions and stuff.
