- The infant mortality rate in Haryana is 7.4 per 1000 births. This means for every 1000 children born, 7.4 children die.
- The total number of children born in Haryana is 5,60,000. So, the number of children who died is calculated as follows:
\[ \text{Number of deaths} = \frac{7.4}{1000} \times 5,60,000 \]
Calculating the number of deaths:
\[ \text{Number of deaths} = 0.0074 \times 5,60,000 = 4,144 \]
Thus, 4,144 children died in Haryana.
Conclusion: The correct answer is (c) 4,144.
