0.78125 l
12.8 l
0.8 l
3.45 l

Explanation:

Step1: Identify the formula

We use multiplication: total juice = juice per batch × number of batches.

Step2: Substitute values

Let juice per batch $a = 0.25$ liter and number of batches $b=3.2$. Then the total juice $V=a\times b = 0.25\times3.2$.

Step3: Calculate

$0.25\times3.2=\frac{1}{4}\times3.2 = 0.8$ liter.

Answer:

C. 0.8 L
