0A spring balance reads \( W_{1} \) when a ball is suspended from it. A weighing machine reads \( W_{2} \) when ball is placed on it. Now
P ball is submerged in a tank of liquid and also suspended with a
W spring balance, if the spring balance reads \( W_{3} \) and the weighing machine reads \( W_{4} \) then which of the following is correct:
(A) \( W_{1}W_{3} \)
(B) \( W_{1}W_{3} \)
(C) \( W_{2}W_{4} \)
(D) \( W_{2}W_{4} \)
