Detailed Solution & Explanation

Let us decode the given relation G @ T # P\displaystyle G \text{ @ } T \text{ \# } P step-by-step using the provided definitions:
1. **Decode G @ T\displaystyle G \text{ @ } T**:
Since "A @ B" means A\displaystyle A is the mother of B\displaystyle B, G @ T\displaystyle G \text{ @ } T means G\displaystyle G is the mother of T\displaystyle T. This implies:
- G\displaystyle G is female.
- T\displaystyle T is the child of G\displaystyle G.

2. **Decode T # P\displaystyle T \text{ \# } P**:
Since "A # B" means A\displaystyle A is the father of B\displaystyle B, T # P\displaystyle T \text{ \# } P means T\displaystyle T is the father of P\displaystyle P. This implies:
- T\displaystyle T is male.
- P\displaystyle P is the child of T\displaystyle T.

3. **Analyze the relationship between G and T**:
Since G\displaystyle G is the mother of T\displaystyle T and T\displaystyle T is male, it follows directly that T\displaystyle T is the son of G\displaystyle G.

Let us evaluate the options:
- **Option a**: "G is mother of P." (Incorrect, G\displaystyle G is the grandmother of P\displaystyle P)
- **Option b**: "P is father of T." (Incorrect, T\displaystyle T is the father of P\displaystyle P)
- **Option c**: "T is son of G." (Correct)
- **Option d**: "P is brother of T." (Incorrect, P\displaystyle P is the child of T\displaystyle T)

Hence, **Option C** is the correct answer.
