The question requires us to identify which features of a strategy are accurately described by the provided statements. Let's evaluate each option:

1. A. It relates to one area of operation: A strategy often encompasses multiple areas of operation for cohesive achievement of organizational goals. Therefore, this statement is not a general characteristic of strategy.
2. B. It requires commitment of the organization: Strategy implementation indeed requires commitment and support from the whole organization. This is an essential feature of any strategic plan.
3. C. It is based mostly on future scenario: Strategy is inherently forward-looking and involves planning based on projections and expectations about the future. Thus, this statement accurately describes a feature of strategy.
4. D. It will not affect future growth of organization: Strategies are designed precisely to influence and enhance future growth. Therefore, this statement is incorrect.
5. E. It is based on expected behaviour of forces in the external environment: Understanding the external environment is crucial for strategic planning, making this statement a true reflection of a strategy's characteristic.

By analyzing the statements, we find that options B, C, and E correctly describe characteristics of a strategy. Therefore, the correct answer is:

This highlights the essential nature of strategic planning, which encompasses organizational commitment, future-oriented thinking, and consideration of external environmental factors.
