Step-by-step explanation:
Seeing as there really isn't a choice to choose between 3 answers, I'll do the math manually and hope it's right.
You need to convert 20% to a decimal. Because 20% is really 20.00, you're going to take the decimal point and move it 2 places to the left --> .20
Because "of" signifies multiplication, you're going to multiply .20 by 45.
So, .2 x 45 = 9
