The load factor of the non-empty hash table is the number of items stored in the table divided by the size of the table.
This is a decision parameter used when we want to rehash or expand the existing hash table entries.
Load factor= $\frac{\text{number of element in hash table}}{\text{hash table size}}$
$\therefore \textrm {Load Factor=$\frac{1000}{10}$}$
Load Factor=100
Option $(A)$ is correct.
