umm that question seems illogical but it said sum so do addition so i say c

Hey there ! 

The Sum is basically addition 

Of two numbers, that is a number  and 12. 

 We don't know what your unknown number is  so will put it as "X"

and 12 = 12


Therefore,  [tex]12 + x [/tex] (option C)  would mostly be your result because it is the sum of those two numbers 

Good luck on your assignment and enjoy your day!
