The point estimate obtained from a sample of which of the following sizes would most likely be closest to the actual parameter value? 15, 45, 150, 75

The point estimate obtained from a sample of which of the following sizes would most likely be closest to the actual parameter value is 150.

It is said that the higher the point estimate, the better. I think this deals with the confidence level of the sample derived from the population. The higher the confidence level, the closer the point estimate is to the actual parameter value.
