Correct Answer:
A. Apply for permits and track approvals
The primary use of an E-Construction Services Portal is to apply for permits and track approvals. These digital platforms are designed by government bodies to streamline the construction process by allowing individuals and businesses to submit applications for building permits, licenses, and other necessary regulatory approvals online. They also provide a mechanism to monitor the status of these applications, enhancing transparency and efficiency. Options B, 'Manage payroll', C, 'Equipment rentals', and D, 'Virtual tours', are functions typically handled by specialized business software, rental companies, or marketing tools, not the core purpose of a government E-Construction Services Portal.
