Answer:</h3><h3>
Option a</h3><h3>
Step-by-step explanation:</h3>
From reading the statements we can rule out the faulty options to reach to the correct answer.
<h3>
Option a:</h3>
There is not any point mentioned in the statement about refuelling the vehicle before checkout. Hence, option "a" is not the rental agency's responsibility. Option "a" is correct.
<h3>
Option b:</h3>
As it is clearly mentioned in the statement that "Upon checkout, the fuel level of the vehicle will be determined by turning the vehicle on and visually inspecting the fuel gauge". Therefore it is the responsibility of the representative and "b" is a wrong option.
<h3>
Option c:</h3>
We can see that it in the agreement it is written that "The approximate fuel level will be recorded on the Check-Out sheet and verified with initials by the vehicle Renter". Therefore it is the responsibility of the representative and "c" is a wrong option.
<h3>
Option d:</h3>
There is a line in the agreement stating that, "One copy of the Check-Out sheet will be given to the customer". Therefore it is the responsibility of the representative and "d" is a wrong option.
