Options

B. `L start M £ N`
C. `L # M $ O £ N`
D. `L £ M start O £ N`

Explanation

To determine which symbol means "L is the mother of N," we need to analyze the symbols provided in the question:

1. **P `start` Q** means P is the father of Q.
2. **P # Q** means P is the sister of Q.
3. **P $ Q** means P is the brother of Q.
4. **P £ Q** means P is the wife of Q.

Now, we need to express "L is the mother of N."

### Step-by-step Solution:

1. **Identify the relationship of L to N**:
- Since we want to express that L is the mother of N, we need to find a way to represent L in relation to N.

2. **Use the wife symbol**:
- The symbol for "wife" is £. If L is the mother of N, we can express this as L being the wife of N's father.

3. **Express N's father**:
- To express L as the mother of N, we need to denote N's father. Let's denote N's father as M. Therefore, we can write:
- L £ M (which means L is the wife of M).

4. **Combine the relationships**:
- Now, since M is the father of N, we can express this as:
- M `start` N (which means M is the father of N).

5. **Final expression**:
- Therefore, combining these two expressions, we can say:
- L £ M `start` N (which means L is the wife of M, and M is the father of N).
- This implies that L is the mother of N.

### Conclusion:
Thus, the expression that means "L is the mother of N" can be represented as **L £ M `start` N**.
