Plz according to the chart above, which of the following statements best describes the relationship between income and literacy in sub-saharan africa? a. higher literacy rates result in higher income levels. b. higher income levels result in higher literacy rates. c. higher literacy rates result in lower income levels. d. higher literacy rates do not necessarily result in higher income levels.

I think that the answer is :

D - Higher literacy rates do not necessarily result in higher income levels.

This is because the Literacy Rate was 91% is Zimbabwe yet the percentage of people living on less than $1/day was 56%.

However, in Mali, the Literacy Rate was only 26% but less people (51%) had such low income levels.

YES IT IS   D -  higher literacy rates do not necessarily result in higher income leaves .
