A
Downwards only
B
Sideways only
C

Answer
Correct option: D.

Liquids exert pressure on every direction based on the kinetic energy of their molecules. Now, in case of mustard oil the pressure exerted will not be much due to low kinetic energy of its molecules, while take the example of cold drinks after getting shaked on the other side, the molecules exert so much pressure its almost like it, flood out of the container.
