○ radical
○ individual
○ random

need help? review these concept resources.

Explanation:

The key detail is that each participant has an equal chance of being placed in any group, which defines random assignment in research—this method ensures unbiased group allocation for testing treatments like the new allergy medication. The other options do not match this core characteristic: "group" is too vague, "radical" is irrelevant, and "individual" does not describe the equal-probability group placement.

Answer:

D. random
