    A)                 

    B)

    C)

    D)

    Correct Answer: C

    Solution :

    [C]
    \[{{V}_{L}}=\frac{{{V}_{0}}}{273}t+{{V}_{0}}\]
    \[[{{V}_{t}}-{{V}_{0}}]=\frac{{{V}_{0}}}{273}t\] \[[{{V}_{t}}-{{V}_{0}}]\,\,\,\frac{273}{{{V}_{0}}}=t\]
    \[\left[ \frac{{{V}_{t}}}{{{V}_{0}}}-1 \right]273=t\]
    \[\frac{273Vt}{{{V}_{0}}}-273=t\]
    \[t\,\,vs\,\,{{V}_{t}}\]                
    \[Slope=\frac{273}{{{V}_{0}}}\]
