Hello!
The answer is: A. 4.5 L
Why?
According to the conversion factor which states that:
![1gal=3.78L](https://img.qammunity.org/2020/formulas/physics/high-school/c15gki47bk8xxgod3pysmkwcxeyfs1564a.png)
It means that we have 3.78 L per each gallon or it's equal to say that we 0.26 gallon per each L.The SI unit for liquid volume is the Liter (L)
Let's make the calculations:
![1.2 gal*(3,78L)/(1gal) =4,54 L](https://img.qammunity.org/2020/formulas/physics/high-school/7k7pj8fdnsjvcibznua2ggebns601vmxnu.png)
So, we have 4.54 L in 1,2 gallons.
Have a nice day!
