Answer:

C. -27+10i

Step-by-step explanation:

The expression is:

(i+3)+6i-3(8-i)

Distribute -3 inside the bracket. This gives,

i+3+6i+(-3\times 8)- (-3\times i)\\ i+3+6i-24-(-3i)\\ i+3+6i-24+3i

Now, we combine the like terms and simplify. This gives,

(i+6i+3i)+(-24-3)=10i+(-27)=-27+10i

Therefore, (i+3)+6i-3(8-i) is equal to -27+10i.
