To determine which alphabet in the Venn Diagram represents "males who are illiterate," we need to analyze the diagram using the given shapes:

• The triangle represents 'Male'.
• The circle represents 'Illiterate'.
• The square represents 'Young'.

We are looking for the section that is only shared by the triangle and the circle, indicating 'males who are illiterate' but not 'young'.

Let's analyze the regions:

• Region A: Inside square, circle, and triangle (Represents 'young illiterate males').
• Region D: Inside triangle and square, outside circle (Represents 'young males' but not 'illiterate').
• Region E: Inside both triangle and circle, outside square (Represents 'males who are illiterate' but not 'young').
• Region F: Inside triangle only (Represents 'males' who are neither 'illiterate' nor 'young').

From the analysis, Region E is the area that corresponds to 'males who are illiterate.'

Conclusion: The correct answer is Option: E.
