Option B, The regular water gummy bear would be larger.
Explanation:
A gummy bear is made up of water and sugar solution. When gummy bear is placed in a solution which has lower water content such as salt water solution, then water within the gummy bear tries to come out of it thereby causing it to shrink from its original shape and size. However, when gummy bear is placed in regular water , then it will swell as water concentration is higher on the outer side as compared to water with in the gummy bear and hence it will swell.
