In C, which data structure is suitable for implementing sparse matrices?ArraysLinked ListsStacksQueues

The most suitable data structure for implementing sparse matrices in C is Linked Lists.

Here's why:

1. Sparse matrices are matrices that have most of their elements as zero. Using arrays to store such matrices would lead to wastage of memory space as you would be storing a lot of zeros.

2. Linked Lists, on the other hand, can be used to store only the non-zero elements along with their position information. This makes them a more memory-efficient data structure for implementing sparse matrices.

3. Stacks and Queues are not suitable for this purpose as they are linear data structures and do not provide the flexibility to store data elements at arbitrary positions.

So, the answer is Linked Lists.
