Please guys i need help. why is option D wrong? I get why option B is correct, based on the explanation given but i thought D was true for all liquids too.

Imagine blood going through the heart. Even though the entire system is a continuous liquid volume, is blood pressure equal throughout? I think that's what they're getting at.

Also think about depth. Fluid pressure increases with depth despite the entire system being part of the same liquid.
