The mixture of solids that can be separated by using both shape and size is oval beads, marbles, and dice (option B).
A mixture in chemistry is any substance that is made up of two or more constituents that can easily be separated using physical means.
Mixtures, unlike compounds, contain substances that retain their chemical composition since there is no chemical bonding.
This makes the components of a mixture separable by physical techniques such as heating, magnetism etc.
Therefore, the mixture of solids that can be separated by using both shape and size is oval beads, marbles, and dice because they are all of different and unique shapes and sizes.
