The correct option among all the options given in the question is option "C" and it can be checked via the above solution.
Step-by-step explanation:
Step 1:
(3x + 12y) + (10x - 5y)
<em>{Distributive property A(B+C)=AB+AC}</em>
-------------------
Step 2:
(3x + 12y) + (-5y + 10x)
<em>{Commutative property A+B = B+A}</em>
-------------------
Step 3:
3x + (12y - 5y) + 10x
<em>{Associative property A+(B+C)=(A+B)+C}</em>
-------------------
Step 4:
3x + 10x + (12y - 5y)
<em>{Commutative property A+B = B+A}</em>
-------------------
Step 5:
13x + 7y
<em>{Simplification}</em>
