Answer 2

THERE ARE 9 ARBITRARY ELEMENTS IN A MATRIX OF ORDER 3.

Explanation:

• A matrix is an array of elements which is written in square brackets.
• It contains rows and columns. The vertical arrangement is called column, and the horizontal arrangement is called row.
• The order of a matrix is the number of rows and columns it will have.
• A matrix of order 1 will have 1 element.
• A matrix of order 2 will have 2x2 elements.
• A matrix of 3 will have 3x3 elements.
• This means that a matrix of order 3 will have 9 arbitrary elements.
• An order 3 matrix has 3 rows and 3 columns, and it can be represented as:

        $\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right]_{3X3}$
