Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that
There are two polynomials :
[tex]17m-12n-1[/tex] and [tex]4-13m-12n[/tex]
We have to add the polynomial :
[tex]17m-12n-1+4-13m-12n\\\\\text{ collect the like terms altogether }\\\\=17m-13m-12n-12n-1+4\\\\=4m-24n+3[/tex]
Hence, Option 'B' is correct.
