Correct answer: B. OnClickListener

In Android development, the most common and recommended way to handle click events on a Button (or any View) is by implementing or setting a View.OnClickListener.

Why B is correct:

• View.OnClickListener has a single method: onClick(View v)
• It’s specifically designed for handling standard tap/click events
• Example usage:

  button.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
          // Handle click
      }
  });
  

  or with lambda (Kotlin/Java 8+):

  button.setOnClickListener(v -> { /* Handle click */ });
  

Why the others are not the best choice:

• A. OnTouchListener – Lower-level touch events (ACTION_DOWN, ACTION_UP, etc.). Overkill for simple clicks and can interfere with gesture detection.
• C. OnLongClickListener – Only for long-press events, not regular clicks.
• D. OnKeyListener – For hardware/software keyboard key events, not view clicks.

Best practice: Always use OnClickListener for standard button clicks (you can also define the click handler directly in XML with android:onClick="methodName").

So, B is definitely the correct answer.
