Answer:
Limitation in Lorenzo's method of research is Option B: It is likely to be time-consuming.
Explanation:
The limitation of the research includes the fact that only one female out of 1500 which are of age group 25-35 have breast cancer. As age increases, the cases for breast cancer increase.
So, if Lorenzo uses this method of age bracket to understand correlation between the age and incidence of breast cancer, it would be time consuming as he needs to research for each group separately and then conclude.
Option D is incorrect as it says that participants would drop out. Option C about cohort difference is also incorrect as cohort differences research means people who born are of same age group share common experience but in this case research is being done on different age groups.
