    How is B more correct than D? Both show that forces between glass and fluid are stronger than those between fluid molecules. Thank you for any insight!

    B. because on the outside. there is more fluid. therefore. more weight that is the fluid putting on the glass. but on the inside. less fluid and the same surface are touching the tube! so it would be easier for the fluid to rise inside the tube. this question is really common sense! i never did this stuff. but its obvious!
