Answer 1

Answer:

rank of singular matrix of order 4 can be the most "1"

Answer 2

Answer:

The rank can be $1,2,3,4$.

Step-by-step explanation:

The rank of a matrix is the dimension of the vector space generated by its columns.

The maximum number of its linearly independent columns or rows of a matrix is called the rank of a matrix.

The rank of a matrix can never exceed the number of its rows or columns.

It is clear from above discussion that the rank of singular matrix of order $4$ can be the most​ $4$. It cannot exceed $4$.

The rank can be $1,2,3,4$.
