Answer:

b. 15 fl. oz

Step-by-step explanation:

From the question, we are told that 3/4 cup of bleach is needed per 1 gallon of water.

Thus:


\begin{gathered} 1\text{ gallon of water requires }(3)/(4)\text{ cup of bleach} \\ \implies2.5\text{ gallons will require }(3)/(4)*2.5\text{ cups of bleach} \\ (3)/(4)*2.5=1(7)/(8)\text{ cups} \end{gathered}

Next, we represent the result in the form of the given options:

Using the standard rate of conversion: 1 cup = 8 fl. oz


\begin{gathered} 1\text{ cup}=8\text{ fl.oz} \\ \implies1(7)/(8)\text{ cups}=8*1(7)/(8)floz=8*(15)/(8)=15fl.oz \end{gathered}

The volume of bleach added to 2.5 gallons of water is 15 fl. oz.
