Option 1 states "Infant mortality rate takes into account the death of infants within a month after birth". Although this statement is partly true, it is incomplete. The Infant Mortality Rate (IMR) considers the death of infants within the first year of life, not just a month.

Option 2 says "Infant mortality rate is the number of infant deaths in a particular year per 100 live births during that year". This statement is correct. It suggests that IMR is a ratio of the number of infant deaths in a specific year to the number of live births during the same year, multiplied by 100. However, the answer indicates that both statements are incorrect.

Alert - correct answer should be option- 2: 2 only. The answer provided initially is incorrect because the second statement is indeed an accurate description of how the Infant Mortality Rate is calculated. Therefore, choice 2 is the correct one.
