$\left( d \right){\text{ None of these}}$

Answer 1

Hint:
A characteristic of interest for an element refers to the set of values obtained by particular observations of a data item. It is related to numerical based data like- height, weights, and so on. So with these, we can now answer it easily.

Complete step by step solution:
It refers to the data item that can be related to numerical based data like height, age, area, and cost. This set of values of a data item is called a variable. These variables can be related to any set of values obtained by the data study or observation of the variable.

Hence, the option $\left( a \right)$ is correct.

Additional information:
Financial specialists utilize measurable data in creating conjectures about the fate of the economy. Statistics is the mathematical realities that assist us with understanding an assortment of circumstances
Data are names or names used to distinguish a property of the component. The raw numbers gathered, dissected, and summed up for introduction and translation
So if the characteristics of observation or we can say the participant differs for group members it is called a variable. Also, the data set can be defined as all the data collected in a particular study. So the elements will be as the entities on which data are collected.

Note:
Normally, a data set comprises the accompanying parts: Element: the substances on which information are gathered. Variable: a quality of interest for the component. Observation: the arrangement of estimations gathered for a specific component. So these are the terms we should know apart from the questions.
