B Correct answer
Explanation

Parenchyma cells are fundamental plant tissue cells characterized by the presence of intercellular spaces between them, which allow for gas exchange and storage. These cells are living, thin-walled, and loosely packed with air spaces. Option A describes collenchyma (thickenings at corners), option C incorrectly phrases 'intercellular wall spaces', and option D is incorrect since parenchyma's defining feature is the intercellular spaces, not all listed characteristics.
