B Correct answer
Explanation

The correct declaration is 'public void update(T updateValue)'. It has the public modifier, void return type, method name 'update', and accepts a parameter of type T named 'updateValue'. Option A returns T instead of void, C lacks public modifier, D lacks the parameter entirely.
