    D.

    Correct option is B

    Given:
    Rupali scored twice as many marks in maths as she did in science.
    Her total marks in maths, science and computer are 234.
    If the ratio of her marks in maths and computer is 4 : 3. 
    Solution:
    Let Marks scored by Rupali in Science = 2x 
    Marks scored by Rupali in Mathematics = 4x
    So, Marks scored by Rupali in Computer = 3x
    Total Marks Scored by Rupali = 234
    2x+ 4x + 3x = 234
    9x = 234
    x= 26
    Rupali's marks in maths = 4x = 4×26=104 \times 26 = 104​​
