Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. are
- In this context, "are" is used to indicate the current state of our requirements.
- It means that regardless of whether our requirements are justified or marginal, we will occasionally feel disheartened when they are not met.
- The other options, "has been," "was," and "were," do not fit the context as effectively as "are" does.
Hence, the correct option would be are.
