yeah i put down A as well coz i was looking at the phon line at the back page, and increase hz to 3000 increases the dB, so i thought it the graph should be decreased since it should be same intensity. lol im not sure. could be wrong. it was defs A or B.

I put down A aswell because I didn't realise it was part of question 9. I just assumed same intensity=same amplitude. My teacher said it was B
