Evaluate the given Assertion (A) and Reason (R) statements:

Assertion (A): The implementation of the Unified Single Window Portal streamlines the regulatory compliance procedure for setting up new enterprises.

Reason (R): The platform consolidates license applications and approvals across diverse government departments into a unified digital interface.

The correct answer is: Both (A) and (R) are correct, and (R) serves as the accurate rationale for (A).

Step 1: Analyze Assertion (A)
Assertion (A) states that the implementation of the Unified Single Window Portal streamlines the regulatory compliance procedure for setting up new enterprises.
This statement is correct. A Single Window Portal acts as a centralized mechanism that reduces bureaucratic hurdles, simplifies procedures, and accelerates business setup by offering a single point of entry for clearances.

Step 2: Analyze Reason (R)
Reason (R) states that the platform consolidates license applications and approvals across diverse government departments into a unified digital interface.
This statement is also correct. The primary technical design of a Unified Single Window System is to integrate various state and central government bodies into one digital platform, enabling investors to apply for permits, submit documents, and track approvals seamlessly in one place.

Step 3: Evaluate the logical relationship between (A) and (R)
The reason why the compliance procedure is streamlined (Assertion A) is precisely because entrepreneurs no longer have to visit multiple departments individually, as all applications and licenses are consolidated into a unified digital interface (Reason R). Thus, Reason (R) provides the correct explanation for Assertion (A).

Conclusion: Both (A) and (R) are correct, and (R) serves as the accurate rationale for (A).
