To find the value of B in the table, we can look at the relationship between the parts and the whole in each column. Let's calculate it step by step:

1. In column A: Part A is 14, Part A is a portion of the Whole which is 20. So, the missing value B in this column can be calculated by subtracting Part A (14) from the Whole (20).
B = Whole - Part A
B = 20 - 14
B = 6

2. In column C: Part C is 28, Part C is a portion of the Whole which is 40. Similarly, we can find the missing value in this column.
B = Whole - Part C
B = 40 - 28
B = 12

3. In column D: Part D is 63, Part D is a portion of the Whole which is B. This time, we need to find the value of B directly.
B = Whole
B = 63

Therefore, the correct value of B in the table is 63.
