Solution:

Understanding the given symbols:

Before moving to the solution of the question, it is important to understand the meaning of the given symbols:

- A B means A is the sister of B
- A-B means A is the brother of B
- A*B means A is the daughter of B

Solution Approach:

To find out the relation between E and D, we need to analyze the given symbols:

- E is the maternal uncle of D, which means E is the brother of D's mother.
- The symbol A*B means A is the daughter of B.

Combining the above two points, we can conclude that:

- If we take A as D's mother and B as E, then D*E would mean D is the daughter of E, which is not true.
- If we take A as E and B as D's mother, then E*D would mean E is the brother of D's mother, which is also not true.
- Therefore, the correct combination would be A as E and B as D's father.
- Then, E*B would mean E is the brother of D's father, which implies that E is the paternal uncle of D.
- But we need to find the relation of E as maternal uncle of D.
- To get the maternal relationship, we need to introduce a common female member in the relation.
- Let us assume F as the mother of D.
- Then, D*F would mean D is the daughter of F.
- Combining the above two points, we get E is the brother of D's father and F is the mother of D.
- Therefore, the correct relation would be D*F-E, which means D is the daughter of F and E is the brother of D's father.

Answer:

Therefore, option 'E' is the correct answer, which shows the relation as D*F E.
