[AI-generated answer — Bot GPT 3.5]

The estimated difference in the expected number of white and red balls in Bowl B can be calculated by finding the difference in the proportion of white balls to red balls selected from Bowl B.

In Bowl B, 40% of the balls selected were red (40 red balls out of 100 total selected) and 60% were white (60 white balls out of 100 total selected).

If there are 500 balls in Bowl B, we can estimate that there are 300 white balls (60% of 500) and 200 red balls (40% of 500) in the bowl.

The estimated difference in the expected number of white and red balls in Bowl B is 300 white balls - 200 red balls = 100.

Therefore, the correct answer is 100.
