Correct

D- reading a scientific study on how much fuel different hybrid cars use

Explanation:

In the case of Dexter, who is researching about hybrid cars and its impact on the environment, for him to determine the best hybrid car, he would need to carry out a formal inquiry.

One of the ways through which this could be done would be by, reading a scientific study already carried out on different hybrid car fuel consumption.

This will offer the information on the best for the environment because, the car with the lowest fuel consumption shows lower gas emission to the environment which lowers the environmental challenges.
