Solution

The load factor for an open addressing technique is b) 1.

Here's why:

The load factor (α) in open addressing hash tables (like linear probing, quadratic probing, and double hashing) is defined as the number of entries (n) divided by the number of slots (m) in the hash table.

α = n/m

In open addressing, we keep storing the elements in the hash table itself. So, at a maximum, every slot in the hash table can be filled. Therefore, the load factor can reach up to 1.

If the load factor exceeds 1 (i.e., α > 1), it means there are more elements to store than there are slots in the hash table, which is not possible in open addressing. Hence, the load factor for an open addressing technique cannot be more than 1.

So, the correct answer is b) 1.
