Concept:
Ownership can be divided not only by rights but also by time. This is called fragmentation of ownership in respect of time.
• One person can have present ownership.
• Another can have future ownership.
• Rights are transferred sequentially.
Step 1: Understand the given situation.
Here:
\[
A \rightarrow B \text{ for life}
\]
means B gets ownership only during his lifetime.
Step 2: Analyze future ownership.
After B's death:
\[
C \text{ gets the property absolutely}
\]
This means C has future ownership rights.
Step 3: Interpret the legal concept.
Ownership is divided:
Presently to B and later to C
Thus, ownership is fragmented according to time.
Step 4: Final conclusion.
Hence, the correct answer is:
\[
\boxed{\text{Fragmentation of ownership in respect of time}}
\]
