Seeking professional help from a therapist or counsellor may also be _________________ (E) in some cases.

The correct answer is helpful.

Step-by-step Explanation:

1. Analyze the context of blank (A):
The sentence reads: "While some amount of stress is _________________ (A) for motivation and productivity, chronic stress can have negative effects on physical and mental health."

2. Understand the logical contrast:
The sentence begins with the subordinating conjunction "While", which establishes a contrast between the two clauses:
- Clause 1: A small/moderate amount of stress has a positive effect (encouraging "motivation and productivity").
- Clause 2: "chronic stress can have negative effects on physical and mental health."

3. Evaluate the given options:
- dispensable: Not necessary or essential; can be done without. (Does not fit the positive contribution to motivation).
- harmful: Causing or likely to cause harm. (Contradicts the contrast created by "While" and the positive terms "motivation and productivity").
- helpful: Giving or providing help; beneficial. (Fits perfectly, as a mild level of stress can serve as a positive driver or booster for motivation and productivity).
- insignificant: Too small or unimportant to be worth consideration. (Does not align logically with driving motivation and productivity).

4. Conclusion:
The word helpful accurately completes the sentence to show that moderate stress is beneficial for productivity, in contrast to chronic stress which is damaging.
