During a physics lab, a plastic strip was rubbed with cotton and became positively charged. The correct explanation for why the plastic strip becomes positively charged is that ...

• the plastic strip acquired extra protons from the cotton.

• the plastic strip acquired extra protons from the charging process

• protons were created as the result of the charging process

• the plastic strip lost electrons to the cotton during the charging process
