To inhibit the growth of tumours,identify the compounds used from the following:
A.EDTA
B.Coordination Compounds of Pt
C.D.Penicilaniulie
D.Cis - Plain
Choose the correct answer from the option given below:

Options

A. `A` and `C` only `
B. `B` and `D` Only `
C. `A` and `B` Only `
D. `C` and `D` only

Answer

To solve the question of which compounds are used to inhibit the growth of tumors, we will analyze each option provided:

1. **EDTA (Ethylenediaminetetraacetic acid)**:
- EDTA is a chelating agent commonly used to bind metal ions in various applications, including medicine for heavy metal detoxification. However, it is not specifically used for tumor inhibition or cancer treatment.

2. **Coordination Compounds of Platinum**:
- Platinum-based coordination compounds are well-known in cancer treatment. They are used in chemotherapy to inhibit tumor growth. These compounds work by interfering with the DNA replication process in cancer cells.

3. **D. Penicillin**:
- Penicillin is an antibiotic used to treat bacterial infections. It does not have any role in inhibiting tumor growth or treating cancer.

4. **Cisplatin**:
- Cisplatin is a specific platinum-based coordination compound that is widely used in chemotherapy. It is effective in treating various types of cancer by preventing the growth and spread of cancer cells.

Based on this analysis, the correct answers that inhibit the growth of tumors are:
- **B. Coordination Compounds of Platinum**
- **D. Cisplatin**

Thus, the correct answer is **BND** (Coordination Compounds of Platinum and Cisplatin).
