Two wooden blocks A and B float in a liquid of density \[{{\rho }_{L}}\]as shown. The distance L and H are shown. After some time, block B falls into the liquid, so that L decreases and H increases. If density of block B is\[{{\rho }_{B}}\], find the correct option.

• A. \[{{\rho }_{_{L}}}={{\rho }_{B}}\]
• B. \[{{\rho }_{_{L}}}>{{\rho }_{B}}\]      
• C. \[{{\rho }_{_{L}}}<{{\rho }_{B}}\]
• D. unpredictable
