  4. D

Answer

While flying
The option 'While flying' is correct because it is the most concise choice that preserves the temporal context and grammatical integrity of the sentence without adding redundant details.

Step-by-Step Solution

1
Read the sentence and evaluate the underlined portion for unnecessary words, repetition, or passive structures.
The original phrase 'During the time when they are flying on this journey' is unnecessarily long and expresses an idea that can be stated much more directly.
ACT English rewards concise and direct phrasing that maintains the original meaning of the passage.
2
Evaluate the choices to find the one that is the most concise while remaining grammatically correct.
The option 'While flying' is short, direct, grammatically correct, and fits perfectly into the sentence. The option 'While flying, which' introduces a grammatical error that creates a fragment. The option using passive voice adds wordiness.
Identifying the option that is both grammatically correct and the most concise determines the correct answer.
