Assertion (A): In hierarchical model, searching for a record is a time-consuming task.

Reasoning (R): Hierarchical model owns to the organization of information/data in a tree-like structure.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

Both A and R are true and R is the correct explanation of A.

Explanation
The hierarchical model arranges data in a tree structure, where each record has a parent-child relationship. Searching for a specific record in such a model may require traversing through multiple levels of the hierarchy, which is time-consuming.
