We know that 1 inch is equal to 2.54 centimeters. Therefore, 1/2 inch (the size of the "dak") is equal to:

(1/2) x (2.54) = 1.27 centimeters

To find out how many "daks" are in 1 centimeter, we can divide 1 by 1.27:

1/1.27 = 0.7874

Therefore, there are approximately 0.7874 "daks" in 1 centimeter. Rounded to three decimal places, this is equal to 0.197. So the answer is B.
