D. (i), (ii) and (iii)

Explanation

### Step-by-Step Solution:

1. **Understanding Antimicrobial Drugs**:
- Antimicrobial drugs are substances that kill or inhibit the growth of microorganisms. They can be classified into different categories based on their application and the type of microorganisms they target.

2. **Identifying Types of Antimicrobial Drugs**:
- There are three main types of antimicrobial drugs:
- **Antiseptics**: These are applied to living tissues to kill or inhibit the growth of microorganisms.
- **Antibiotics**: These are taken internally (eatable) to kill or inhibit the growth of microorganisms within the body.
- **Disinfectants**: These are used on non-living surfaces to kill or inhibit the growth of microorganisms.

3. **Examples of Each Type**:
- **Antiseptics**: An example is Dettol, which is commonly used on wounds to prevent infection.
- **Antibiotics**: An example is Penicillin, which is used to treat bacterial infections within the body.
- **Disinfectants**: An example is Lysol, which is used to clean and disinfect surfaces.

4. **Conclusion**:
- Since all three categories (antiseptics, antibiotics, and disinfectants) are considered antimicrobial drugs, the correct answer to the question is that antimicrobial drugs include all three options.

### Final Answer:
Antimicrobial drugs include:
- (i) Antiseptics
- (ii) Antibiotics
- (iii) Disinfectants

Thus, the correct answer is that all three options are correct.
