The correct option is A

Finding the value of function:

Here we use the formula tan(A+B)=tanA+tanB1-tanAtanB

tan225°=tan(203°+22°)=tan(180°+45°)=tan45°=1

tan(203°+22°)=tan203°+tan22°1-tan203°tan22°=1tan203°+tan22°=1-tan203°tan22°tan203°+tan22°+tan203°tan22°=1

Hence option(A) is the correct answer .
