Which e commerce company partnered with the National Highways Authority of India NHAI to enable cashless payments at national and city toll plazas through electronic means?

Introduction / Context:
This question relates to the promotion of digital payments in India, particularly in the context of road travel and toll collection. As part of the push towards a less cash economy, the National Highways Authority of India NHAI teamed up with a popular payment platform to make toll payments easier and cashless. Awareness of such partnerships is important in exams that cover digital initiatives, banking awareness and infrastructure.

Given Data / Assumptions:

• The partner organisation is an e commerce or digital payments company.
• The partnership with NHAI was to enable cashless payments at national and city toll plazas.
• The options are Paytm, Mobikwik, Freecharge and Oxigen.
• We assume the question refers to the widely publicised arrangement that allowed using a wallet or similar service for toll payments.

Concept / Approach:
The approach is to recall which of these digital payment companies was prominently associated with toll payments and NHAI. Paytm, a leading digital wallet and payments platform, entered into an agreement with NHAI to facilitate electronic toll payments and to integrate with systems like FASTag for smoother travel. Although other companies such as Mobikwik, Freecharge and Oxigen also operate in the digital payment space, the widely reported partnership with NHAI for toll plaza cashless payments was with Paytm.

Step-by-Step Solution:
Step 1: Identify that NHAI manages national highways and toll plazas in India.Step 2: Recall news about the push towards electronic toll collection and the introduction of tags and digital wallets.Step 3: Remember that Paytm was one of the most visible partners in this initiative, offering users the ability to recharge and pay tolls digitally.Step 4: Note that while Mobikwik, Freecharge and Oxigen are also digital payment platforms, they were not highlighted in the same way in connection with NHAI toll plazas.Step 5: Match this recollection with the options and select Paytm as the correct answer.

Verification / Alternative check:
Media reports at the time of the partnership emphasised that Paytm was working with NHAI to simplify toll payments and support electronic toll collection systems. Users could link their Paytm accounts to tags or toll accounts to pay automatically at toll booths, reducing congestion and the need for cash. No similar level of coverage associated Mobikwik, Freecharge or Oxigen with a primary nationwide toll partnership with NHAI, supporting the choice of Paytm.

Why Other Options Are Wrong:

• Mobikwik is wrong because, although it is a recognised digital wallet, it was not the main platform announced in partnership with NHAI for toll plazas in this question context.
• Freecharge is wrong because it was more associated with mobile recharges and other payments and not specifically highlighted for NHAI toll arrangements.
• Oxigen is wrong because this payments platform also did not become the headline partner for NHAI cashless toll payments in the way Paytm did.

Common Pitfalls:
Some candidates assume that any famous wallet could be the answer and guess based on personal use rather than recall of the specific partnership. Others may confuse later developments in digital payments with the particular event referenced in the question. To avoid such errors, it is helpful to link specific government collaborations with the correct company names and to revise these pairings regularly.

Final Answer:
Paytm is the e commerce and digital payments company that partnered with NHAI to enable cashless payments at national and city toll plazas.
