Explanation:

• Radiocobalt (like Co - 60) is mainly used in radiation therapy for cancer but not typically for studying fertilizer absorption.
• Radium was historically used in cancer treatment but has no role in studying fertilizer absorption.
• Aluminum has no significant role in either studying fertilizer absorption or cancer treatment.
• Radiophosphorus (P - 32) can be used as a radioactive tracer to study how plants absorb phosphorus - based fertilizers. Also, it can be used in cancer treatment, especially for certain blood - related cancers, as it can target and destroy rapidly dividing cancer cells.
