A physcial quantity \[x\] depends on quantities \[y\] and \[z\] as follows: \[x=Ay+B\tan Cz\], where \[A,\,B\] and \[C\] are constants. Which of the following do not have the same dimensions [AMU (Engg.) 2001]

• A.             \[x\] and \[B\]  
• B.             \[C\] and \[{{z}^{-1}}\]
• C.             \[y\] and \[B/A\]          
• D.             \[x\] and \[A\]
