Answer

To determine which vaccines are injected to babies at the ages of 1.5 months, 2.5 months, and 3.5 months, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Vaccination Schedule**:
- Vaccination schedules are established guidelines that indicate when certain vaccines should be administered to infants and children. For infants, specific vaccines are given at certain ages to ensure they develop immunity against various diseases.

2. **List the Vaccines Administered at 1.5, 2.5, and 3.5 Months**:
- At 1.5 months (or 6 weeks), the following vaccines are typically administered:
- DPT (Diphtheria, Pertussis, and Tetanus)
- IPV (Inactivated Polio Vaccine)
- At 2.5 months (or 10 weeks), the following vaccines are typically administered:
- DPT
- Hib (Haemophilus influenzae type b)
- IPV
- At 3.5 months (or 14 weeks), the following vaccines are typically administered:
- DPT
- Hib
- IPV

3. **Analyze the Options Provided**:
- The options given in the question are:
- A) Polio and BCG
- B) BCG and DPT
- C) Hib, DPT, and Polio
- D) BCG and Hepatitis B
- Based on the vaccination schedule:
- Option A is incorrect since BCG is not typically given at these ages.
- Option B is incorrect for the same reason.
- Option C is correct as it includes DPT, Hib, and Polio, which are administered at the specified ages.
- Option D is incorrect as BCG is not administered at these ages.

4. **Conclusion**:
- The correct answer is Option C: DPT, Hib, and Polio.
