Improve the bracketed part of the sentence by choosing the correct option. If no improvement is required, select "No improvement". Sentence: The telecom sector is the backbone to the Digital India vision and it deserves an (enabled) regulatory environment.

Introduction / Context:
This sentence improvement question focuses on choosing the correct adjective to describe the type of regulatory environment that the telecom sector deserves. The current bracketed word enabled sounds awkward in this context. You must select the form that accurately expresses the idea of regulation that actively supports and facilitates growth.

Given Data / Assumptions:

• The sentence is: The telecom sector is the backbone to the Digital India vision and it deserves an enabled regulatory environment.
• The bracketed word is enabled.
• Options: enabling, enable, able, No improvement.
• We assume the intended meaning is that the regulatory environment should be supportive and facilitative, not simply one that has been enabled by someone else.

Concept / Approach:
Enabled is the past participle of enable and usually describes something that has been made able by an external agent. In policy language, however, the usual expression is enabling environment, meaning an environment that enables or facilitates growth and innovation. Therefore, the correct adjective here is enabling. This describes the nature of the regulatory environment itself as supportive, rather than merely indicating that someone enabled it in the past.

Step-by-Step Solution:
Step 1: Identify the desired quality of the regulatory environment: it should actively help the telecom sector to grow and serve as the backbone of the Digital India vision.Step 2: Recall that in development and policy documents, phrases like enabling policy framework and enabling ecosystem are standard.Step 3: Replace enabled with enabling and read the sentence again: it deserves an enabling regulatory environment, which now sounds natural and matches policy writing style.Step 4: Consider enable, which is a bare verb form and cannot be used directly before a noun as an adjective in this way.Step 5: Consider able, which describes the capability of a person or thing, not the role of an environment in facilitating growth. Therefore, enabling is the only option that improves the sentence.

Verification / Alternative check:
Check similar expressions: Governments aim to create an enabling environment for entrepreneurship, and The reforms are designed to build an enabling framework for investment. In both cases, enabling describes an environment that helps other activities succeed. Substituting enabled in these sentences would make them sound odd. The same pattern applies to the sentence about the telecom sector, confirming that enabling is preferred.

Why Other Options Are Wrong:
Enabled focuses on the fact that something has been made able by someone else, which is not the intended emphasis here. It would be more appropriate in a sentence like This feature is enabled by default in the software. Enable is a verb and cannot stand directly before regulatory environment as an adjective. Able suggests capability but not a supportive or facilitative role. It is used for people or entities that can do something, such as an able administrator, not for the environment or framework itself.

Common Pitfalls:
Students often confuse participle adjectives like enabling and enabled, especially when both forms look similar. The key is to remember that enabling usually describes something that helps others, while enabled describes something that has been given capability. In policy and economic contexts, enabling environment is a standard phrase that you should recognise and use in questions like this.

Final Answer:
The bracketed word enabled should be replaced with enabling, so option A is correct.
