Which of the following is considered to be an anticancer species?

Options

A.
B.
C.
D.

Explanation

To determine which of the following compounds is considered to be an anticancer species, we will analyze the options provided and identify the correct answer based on known information about anticancer drugs.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for an anticancer species among the given options. We need to identify which compound is recognized for its use in cancer treatment.

2. **Identify Known Anticancer Compounds**: One of the well-known anticancer drugs is cisplatin. Cisplatin is a coordination compound that has been widely used in chemotherapy for treating various types of cancer.

3. **Cisplatin Structure**: The chemical formula for cisplatin is [Pt(NH3)2Cl2]. In this compound:
- **Pt** (platinum) is the central metal atom.
- It is coordinated with two ammonia (NH3) ligands and two chloride (Cl) ligands.
- The "cis" configuration means that the two NH3 ligands are adjacent to each other.

4. **Confirm the Isomer**: The question specifies that we are looking for the cis isomer of the compound. The cis isomer of [Pt(NH3)2Cl2] is indeed used as an anticancer drug, while the trans isomer is not.

5. **Select the Correct Option**: If the options provided include cisplatin or its equivalent structure, we can confidently select that as the answer. Based on the information, the correct answer is:
- **Cisplatin (option C)**.

### Final Answer:
The anticancer species among the options is **Cisplatin** (Pt(NH3)2Cl2).
