Final answer:
In the analogy where a car relates to a driver, the parallel term is a plane as it relates to a pilot. The correct answer is 'd. plane'.
Step-by-step explanation:
The analogy in question is: car is to driver as plane is to pilot. So, the correct answer is d. plane. Just as a driver operates a car, a pilot operates a plane. This type of analogy is used to illustrate the relationship between one pair of words and to find a parallel relationship in another pair of words.
The analogy draws a parallel between a car and its driver to something related to a pilot. In this case, just as a car is operated by a driver, a plane is operated by a pilot. So, the correct completion for the analogy is "plane."
