Form J25 English Question

Does anyone remember this question from form J25 English section? The passage was about Mount Everest height dispute, and the question was asking about redundancy and it had to do with some Chinese scientists comparing the height of the mountain similarly. Did you put answer D (compared the height, similarly), or answer A (no change; similarly compared the height)? I'm just confused because I remember both answers being the exact same except the words flipped. PLEASE RESPOND if u remember!!! Also, put any other questions from J25 down that you need answered!
