IMO its A.
Since its a statistician's conclusion and should be based on data available and not the general probability - hence B, C and E are not valid reasons.
D says number of plane flight or train trips are not give - which cannot be used against number of miles give for car. Since the statistic for car is given in terms of miles, all the other journey also should have the death in terms of miles.
A says there is no such common denominator it refutes the conclusion.

What if only 40 thousand people travel by car but 100 thousand people travel by plane and 300 thousand travel by train then in this case the current argument will be wrong. We need a common denominator to compare.
D talks about number of trips. Even if we know number of trips what difference is this going to make till we dont know the statistical data in terms of people.
Moreover trip is vague term it didn't give any idea about the distance. A trip can be of 200 miles or can be of 1500 miles.

The safety of any mode would be caculcated as = Number of casualities/Number of miles travelled
If there are less casualities as one travels more miles it means that mode is safer.
Clearly ,there is a confusion among A and D but D brings in the number of trips into scene which is insufficient to derive any information about number of miles travelled so A is the most favorable answer.
