Show answer & explanation
Correct answer: B
In matrix theory, a 2-dimensional array (matrix) with a relatively high proportion of zero entries is called a Sparse Matrix. This is because most of the elements are zero, and such matrices are often stored in specialized formats to save memory. On the other hand, a matrix with a low proportion of zero entries is called a Dense Matrix, as most of the elements are non-zero and require standard storage methods.
