MCQ
The transpose of a row matrix is :
  • A
    zero matrix
  • B
    diagonal matrix
  • ✓
    column matrix
  • D
    row matrix
✓

Answer

Correct option: C.
column matrix
Transpose of row matrix Let $ \text{A}=\begin{bmatrix}\text{x} &\text{amp; y} &\text{amp; z} \end{bmatrix}$ be a row
matrix $\text{A}^\text{T}=\begin{bmatrix}\text{x}\\\text{y}\\\text{z}\end{bmatrix}$Clearly $\text{A}^\text{T}$ is a column matrix
$\therefore$ Transpose of row.
