Equal masses (W gram each) of three non- reacting gases X,Y and Z were mixed in sealed rigid container and total pressure at a given temperature T was found to be 'P' atmosphere Now '2W' gram of X is further added to same container and temperature was raised to '2T' At '2T' temperature new pressure was found to be '4P' atmosphere Now '3W' gram of Y was added further and temperature was raised to '4T' New pressure was found to be '12P'
In final conditions partial pressure of 'Z' is:

Options

A. `P/3`
B. `(3P)/4`
C. `(2P)/3`
D. `P/6`
