Final answer:
The component that is NOT a part of attenuation is resolution.
Step-by-step explanation:
The component that is NOT a part of attenuation is c. Resolution. Attenuation refers to the decrease in intensity or amplitude of waves as they travel through a medium. The components of attenuation include reflection, where incident waves bounce back off a surface, scattering, where waves are redirected in different directions, and absorption, where waves are absorbed by a medium and converted into other forms of energy such as heat.
