Step by step solution

01

Given Information

The given graphs

02

Explanation for correct option

The graph shows that the bars are centred around the value and have the least fluctuation (therefore the smallest overall width) (indicated by the arrow).

As a result, histogram A would lead to an excellent parameter estimation.

As a result, the best solution is (A)

03

Explanation for incorrect option

The option (b) and (c) is not the correct answer.
