When viewed from the window of a speeding train,

Comparison Analysis:(A) the speed with which nearby objects move seems faster than that of
the speed with which nearby objects <--> that (the speed) of more distant objects
(B) the speed that nearby objects move seems faster than for
the speed that nearby objects move --> nearby objects move the speed --> we need some preposition here, such as "with"
(C) the speed of nearby objects seems faster than
the speed of nearby objects <--> more distant objects --> incorrect
(D) nearby objects' speeds seem to be faster than those of
nearby objects' speeds <--> those (speeds) of more distant objects
(E) nearby objects seem to move at a faster speed than do
nearby objects seem <--> more distant objects do (seem)
Question:
In A and D, do we need to repeat the verb "move" and "seem" or it is common verb for both so it is optional. Can any expert comment. Thanks!

In options A and D, we are comparing the speed of X to the speed of Y. Hence the use of “that/those of” is correct.
Eg- The surface of Earth is similar to that of Mars.
"move" is not a verb in option A. Moreover, we are not comparing an action but "speed"
In option E, we are comparing the action- move.
Hence we use the verb “do” to replace “move” and make the comparison parallel.
Eg- Cotton materials absorb more water than synthetic materials do.
