Options

A.
B.
C.
D.

Explanation

To determine which of the given options is considered to be an anticancer species, we need to identify the compound known for its anticancer properties. The compound in question is cisplatin.

### Step-by-Step Solution:

1. **Identify the Anticancer Compound**:
- The most well-known anticancer compound is cisplatin, which is used in chemotherapy to treat various types of cancer.

2. **Understand the Structure of Cisplatin**:
- Cisplatin is a coordination compound that contains platinum (Pt) as the central metal atom. Its chemical formula is [Pt(NH3)2Cl2].
- In this compound, there are two ammonia (NH3) molecules and two chloride (Cl) ions coordinated to the platinum atom.

3. **Cis Configuration**:
- The term "cis" refers to the arrangement of the ligands around the platinum atom. In cisplatin, the two NH3 molecules are adjacent to each other, and the two Cl ions are also adjacent, which is crucial for its biological activity.

4. **Conclusion**:
- Since cisplatin is recognized for its effectiveness in cancer treatment, it is indeed considered an anticancer species.

### Final Answer:
Cisplatin is considered to be an anticancer species.
