C.  

Step-by-step explanation:

Line of best fit (trendline) : a line through a scatter plot of data points that best expresses the relationship between those points.

All the given options for the line of best fit are linear equations.

Therefore, we can add the line of best fit to the graph (see attached), remembering to have roughly the same number of points above as below the line.

Linear equation:  

(where is the slope and is the y-intercept)

From inspection of the line of best fit, we can see that the y-intercept (where x = 0) is approximately 200.  So this suggests that either option C or option D is the solution.

We can also see that slope (gradient) is approximately 1, as for every +100 increase in x, y increases by +100.

Therefore, this suggests that C is the solution and that the closest approximation to the line of best fit is

Note:-

Graph must not be drawn to scale so taken imaginary coordinates most near to accurate

So the cordinates are

Mark the change between x and y

So

the relationship is

Option C
