Answer:

The answer is option C

Explanation:

From the question we are told that

12 resistors + 20 insulators + 8 memory chips → 4 circuits

Now from this expression we can see that

       20 insulators produces 4 circuit

And we are being as to calculate how many circuit  5 insulators would produce

     S using basic relation we have that

                       20 is to  4

          then      5  is to    ?                             let call ? = x

  applying cross multiplication we have that

                20  ×  x = 4 × 5

  Therefore   x =  (4 ×  5)  ÷   20

                      x   =   1 circuit

We can see from our calculation that 5 insulators would produce one circuit
