22. Car owners who inflate their tires properly can substantially boost their vehicles’ fuel efficiency, since the increase in car-road friction can waste up to five percent of car fuel by underinflation.
A. Car owners who inflate their tires properly can substantially boost their vehicles’ fuel efficiency, since the increase in car-road friction can waste up to five percent of car fuel by underinflation.
B. Because the underinflaton of tires can waste up to five percent of a car’s fuel by increasing car-road friction, car owners can substantially boost their vehicles’ fuel efficiency by properly inflating the tires.
C.Their vehicles’s fuel efficiency is substantially boosted by car owner through the proper inflation of tires that , when underinflated ,can waste up to five percent of car fuel by an increase in car –road friction.
D.The proper inflation of tires by car owners, due to the fact that underinflation can waste up to five percent of a car’s fuel by the increase of car-road friction, can substantially boost their fuel efficiency.
E. Because up to five percent of a car’s fuel are wasted through the increase s in car-road friction when the tires are underinflated, car owners properly inflating tires can substantially boost their fuel efficency.

a和b有意思上的区别，a说给自行车打饱气的人可以提高。。。效率。b说人们可以通过给自行车打饱气提高。。效率。从逻辑意思上来说明县应该选b.

agree! There are some differences between these two chioces.

The subordinate sentence of the chioce A is also illogical.
Omitting modification, we get the original sentence as below:

Car owners ...can ... boost their vehicles’ fuel efficiency, since the increase ...can waste up to five percent of car fuel by underinflation.

It's illogically to say that "increase can waste car fuel by underinflation." , and "increase" definitely cannot take the responsibility for "underinflation" as well. Also this sentence does not indicate "underinflation" for what.
