Answer:
The correct option is A.
Step-by-step explanation:
In a scatter plot the best fit curve in known as regression curve. Types of regression curves are
1. Linear regression line : If the best fit of a data is a straight line, then it is known as linear regression line.
2. Quadratic regression : If the best fit of a data is a U-shape curve, then it is known as quadratic regression.
3. Exponential regression : If the best fit of a data is an exponential curve, then it is known as exponential regression.
From the given graph it is clear that scatter data forms a U-shaped curve. Since the best fit of a data is a U-shape curve, therefore the quadratic regression model is best for the data.
Thus, option A is correct.
