To find the conditional distribution of blood pressure level for employees between 30 and 49, we need to look at the row of the table that corresponds to this age group and calculate the percentage of each blood pressure level out of the total for that age group.

For employees between 30 and 49, the total number of individuals is 300.

To find the percentage for each blood pressure level, divide the frequency by the total and multiply by 100.

Low: (45/300) x 100 = 15%
Normal: (153/300) x 100 = 51%
High: (102/300) x 100 = 34%

Therefore, the conditional distribution of blood pressure level for employees between 30 and 49 is 15% low, 51% normal, and 34% high. The closest answer choice to this is D: 21% low, 51% normal, 28% high.
