The expected number of white balls selected from Bowl B can be calculated as (60/100)*500 = 300 white balls.
Similarly, the expected number of red balls selected from Bowl B can be calculated as (40/100)*500 = 200 red balls.
The estimated difference in the expected number of white and red balls in Bowl B is 300 - 200 = 100.
Therefore, the answer is b. 100.
