Answer: The correct option is C.
Explanation:
It is given that Jonas made the following matrix of temperatures for the first 4 days of January and for the first 4 days of February.
Let the matrix A and B represents the temperatures for the first 4 days of January and February respectively.
![A=\begin{bmatrix}6 & -3 & 3 & -1\end{bmatrix}](https://tex.z-dn.net/?f=A%3D%5Cbegin%7Bbmatrix%7D6%20%26%20-3%20%26%203%20%26%20-1%5Cend%7Bbmatrix%7D)
![B=\begin{bmatrix}1 & -3 & -5 & -6\end{bmatrix}](https://tex.z-dn.net/?f=B%3D%5Cbegin%7Bbmatrix%7D1%20%26%20-3%20%26%20-5%20%26%20-6%5Cend%7Bbmatrix%7D)
The difference of January and February is defined by the matrix A-B.
To subtract two matrices, we subtract all the corresponding elements.
![A-B=\begin{bmatrix}6-1 & -3+3 & 3+5 & -1+6\end{bmatrix}](https://tex.z-dn.net/?f=A-B%3D%5Cbegin%7Bbmatrix%7D6-1%20%26%20-3%2B3%20%26%203%2B5%20%26%20-1%2B6%5Cend%7Bbmatrix%7D)
![A-B=\begin{bmatrix}5 & 0 & 8 & 5\end{bmatrix}](https://tex.z-dn.net/?f=A-B%3D%5Cbegin%7Bbmatrix%7D5%20%26%200%20%26%208%20%26%205%5Cend%7Bbmatrix%7D)
It is the option C.
