Hint: We know volume measure in Liters or milliliters. So, we Use Metric conversion to convert Liters into milliliters. 1Litre=1000 milliliters.

Complete step-by-step answer:
Rohan bought a 50 liters container of oil. So, the volume of oil in the container is equal to 50 Liters.
As we can see from option all answers in milliliters. So, we convert the volume of oil in the container to milliliters.
Total Volume of oil in container $ = 50L = 50 \times 1000milliliters = 50000milliliters$
Then he used 44300 milliliters of oil from the container. So, the volume of oil in the container decreases from 50000 milliliters.
Volume of oil used from container $ = 44300milliliters$
Volume of oil left in the container = total volume of oil in container- volume of oil used from container .
Volume of oil left in the container $ = \left( {50000 - 44300} \right)milliliters$
$ \Rightarrow 5700milliliters$
 The volume of oil left in the container is 5700 milliliters.
So, the correct option is (a).

Note: Whenever we face such types of problems we use some important points. First we convert all units of volume as required in answer then subtract the used volume from the total volume. So, we can get the required answer.
