A retailer stores product-by-branch sales in matrix $S$ and wants next year’s targets: 25% growth everywhere. Which single expression produces the target table?

D. $1.25\,S$

$1.25\,S$ multiplies every cell by 1.25. Adding the number 0.25 to a matrix is not even defined entrywise growth, and $25S$ would demand 2,400% growth from the sales team.
