The correct option is C 4y−25
Step 1:–––––––––
First we need to multiply the variable 'y' by 4, i.e, 4×y=4y
∴4y is the required product.
Step 2:–––––––––
Now, we need to subtract 25 from the product 4y. This results in 4y−25.
4y−25–––––––– is the required algebraic expression.
Therefore, option (c.) is the correct answer.
