Understanding the Relationships
To analyze the statements given:
- J is the brother of K.
- K is the brother of L.
- M is the father of J.
From these statements, we can derive several key relationships.
Key Relationships Derived
- J, K, and L are siblings.
- M, being the father of J, is also the father of K and L, as they are all siblings.
Now, let’s evaluate the options provided:
Options Analysis
- a) L is the brother of J
- This statement cannot be definitely true. L could be a brother or a sister. The gender of L is not specified in the information we have.
- b) K is the son of M
- This statement is definitely true. Since M is the father of J, and J and K are brothers, K must also be the son of M.
- c) J is the brother of L
- This statement is definitely true. Since J and L are siblings through K, they must be brothers or sisters.
- d) K is the brother of J
- This statement is definitely true as per the first statement.
Conclusion
The only statement that cannot be definitively established is option a, as L's gender is not specified and could potentially be female. Therefore, while J and L are siblings, we cannot confirm L is a brother.
