The order of the matrix `[(a,b,c,d)] ` is ________.

Options

A. `5xx1`
B. `2xx3`
C. `1xx4`
D. `4xx1`

Answer

To determine the order of the matrix `[(a, b, c, d)]`, we follow these steps:

### Step 1: Identify the Structure of the Matrix
The given matrix is `[(a, b, c, d)]`. This is a single row containing four elements.

### Step 2: Count the Number of Rows
In this matrix, there is only **1 row**.

### Step 3: Count the Number of Columns
In this matrix, there are **4 columns** (the elements a, b, c, and d).

### Step 4: Write the Order of the Matrix
The order of a matrix is defined as the number of rows multiplied by the number of columns. Therefore, the order of this matrix is:
\[ \text{Order} = \text{Number of Rows} \times \text{Number of Columns} = 1 \times 4 \]

### Final Answer
Thus, the order of the matrix `[(a, b, c, d)]` is **1 x 4**.
