Final answer:
Cisplatin is the platinum-based heavy metal complex that is cell cycle non-specific among the options provided.
Step-by-step explanation:
The heavy metal complex of platinum that is cell cycle non-specific you are asking about is Cisplatin. Cisplatin is a platinum-based chemotherapeutic drug that is used to treat various types of cancers by causing DNA damage. Unlike some chemotherapeutic agents that target specific phases of the cell cycle, cisplatin affects cells regardless of the stage of the cell cycle, making it cell cycle non-specific.
Other options such as Carboplatin and Oxaliplatin are also platinum-based and have similar mechanisms, but Cisplatin is the correct answer in this context.
Cyclophosphamide, on the other hand, is not a platinum-based drug but rather an alkylating agent, another type of chemotherapy medication.
