Answer options

• A. stereotactic radiation treatment.
• B. proton beam treatment.
• C. brachytherapy.
• D. external beam radiation.

Correct answer: C

Explanation

Stereotactic radiation treatment and external beam radiation involve delivering radiation from outside the body, and proton beam treatment uses protons instead of radioactive sources, so they do not match the definition provided.
