Given the following table: $\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\text { Supplement }$ Strain A + - + - Strain B + + + - Strain C + + + + Strain D - - + - where numbers 1 through 4 indicate four supplements that must be added to sustain growth of the organism.Determine a possible metabolic pathway that would give the results seen for the four mutant strains,A through D.
