Here are the essential concepts you must grasp in order to answer the question correctly.
Resonance Structures
Resonance structures are different Lewis structures for the same molecule that depict the same arrangement of atoms but differ in the placement of electrons. These structures help illustrate the delocalization of electrons within a molecule, which can stabilize the overall structure. Understanding resonance is crucial for predicting the reactivity and stability of radicals, as it shows how electron density can be distributed across different atoms.

Radicals
Radicals are species that contain an unpaired electron, making them highly reactive. They can be formed through various processes, such as homolytic bond cleavage. In the context of resonance, radicals can have multiple resonance contributors, which can help stabilize the radical by delocalizing the unpaired electron across different atoms, thus lowering the overall energy of the molecule.

Electron Delocalization
Electron delocalization refers to the spreading of electron density across multiple atoms in a molecule, rather than being localized between two atoms. This phenomenon is a key feature of resonance and contributes to the stability of radicals and other reactive intermediates. By understanding how electrons can be shared among different atoms, one can better predict the behavior and reactivity of organic compounds.
