D. 5

Explanation:

The unit rate of unit A to unit B is given by the division of the amount needed of unit A divided by the amount needed of unit B.

In this question:

Unit A: Lemonade

Amount: 1/2 liter

Unit B: Cranberry juice

Amount: 1/10 liter

Unit rate:

`(A)/(B)=((1)/(2))/((1)/(10))=(1)/(2)\ast(10)/(1)=(1\ast10)/(2\ast1)=(10)/(2)=5`

The answer is: D. 5
