Select the option that is true regarding the following two statements labelled Assertion and Reason. Assertion (A): A dietary survey is conducted to assess the quantities of food items and nutrients consumed by an individual or the family. Reason (R): The main methods used to collect data on individual food intake are 24-hour recall and food frequency questionnaire.

Correct option is B

Dietary surveys are a key tool in nutritional assessment used to evaluate the types and quantities of food and nutrients consumed by individuals or families over a specific period.
They help in identifying deficiencies, excesses, and dietary patterns for public health interventions.
Thus, the Assertion is true.
The Reason is also true – two of the most commonly used tools in dietary assessment are:
24-hour dietary recall: A structured interview to record all foods and beverages consumed in the previous 24 hours.
Food Frequency Questionnaire (FFQ): Assesses habitual intake over a longer period, such as weeks or months.
However, the reason does not fully explain why a dietary survey is conducted. It only describes data collection methods, not the purpose stated in the assertion.
Therefore, both A and R are true, but R is not the correct explanation of A. Correct answer: Option (b).
