Correct Answer – Option 1 : (A) and (R) both are correct and (R) is the correct explanation of (A).
Explanation:-
- The nutritional status of an individual reflects the extent to which their physiological needs of nutrients have been covered at a particular life stage.
- Dietary assessment and nutritional status are traditionally measured by means of dietary intake data, such as 24-h dietary patterns.
- Biochemicals provide a more proximal measure of nutrient status than dietary intake. So by, Generally speaking, a nutritional biomarker is a characteristic that can be objectively measured in different biological samples and can be used as an indicator of nutritional status with respect to the intake or metabolism of dietary constituents

Correct Answer – Option 4 : 1921
Concept:-
- The year 1921 is often referred to as the “Year of the Great Partition”, the last period in which India’s population declined drastically due to the effects of the famine.
- After 1921, India’s population growth remained steady.
- The year 1921 is known as the demographic split because prior to this year, the population was not stable, sometimes it increased and sometimes decreased.
- Before 1921 the scale of population growth was generally low. But after this year there has been a considerable and continuous increase in the population.
- After that, it is growing rapidly. Hence the year 1921 is rightly called the Year of the Demographic Divide or the Great Divide.

Correct Answer – Option 2 : Childbirth and lactation
Concept:
Explanation:
- Oxytocin is synthesized in hypothalamic magnocellular neurons and released from the posterior pituitary into the bloodstream.
- Gq coupled G-protein Coupled Receptor (GPCR) is the oxytocin receptor.
- The receptors’ activation leads to the influx of calcium ions that lead to smooth contraction.
- Therefore, it causes contraction of the smooth muscles of the uterus.
- These contractions also reduce the bleeding.
- Oxytocin also acts on myoepithelial cells in the breast, resulting in the contraction of muscles and ejection of the milk.
