C. 28 adult tickets; 42 child tickets

Step-by-step explanation:

Let x = Number of child ticket

y= Number of adult tickets

As per given , we have the following system of linear equations :

$x+y=70---(1)\\\\ 8x+12y=672----(2)$

Multiplying 8 on both sides of equation (1), we get

8x+8y=560----(3)

Subtract (3) from (2) , we get

$4y=112\\\\\Rightarrow\ y=\dfrac{112}{4}=28$

Put value of y in (1) , we get

$x+28=70\\\\\Rightarrow\ x=70-28=42$

Hence, the correct answer is

C. 28 adult tickets; 42 child tickets
