A quick question on RMS speed of gas molecules

  1. Feb 1, 2016 #1
    1. The problem statement, all variables and given/known data
    As attached.

    2. Relevant equations


    3. The attempt at a solution
    I chose A but the correct answer is E.(Actually I thought both of them were correct)
    From the graph provided,it is clear that the turning point corresponds to the largest proportion of molecules,so is the corresponding speed = rms speed?If yes,then A must be true?
