1. 假設你而家淨係得 Y, 冇 X , 如果你要多1個 X 你最多肯比比 1個Y (MRS, keep utility unchange),  但係實際上你要比1.2 個Y 先買到1 個X, 咁你實唔肯買架, 所以當relative price (1.2Y) > MRS (1Y) 時, 你就唔會要X, 淨係keep Y

Q2: I think should be D.

As the budget line is downward sloping, these 2 goods, in my opinion, should be good. (it seems not reasonable to forgive one bad or neuter in order to get one good .... ). So, only D is the correct answer.
