Windows is an operating system built by Microsoft. Chrome and Android are operating systems built by Google. MacOS (Macbook pro etc) and iOS (iPhone, iPad, Apple Watch etc) are operating systems built by Apple.
Engineers build applications or apps for all of the above operating systems (OS). For example, Microsoft Word menus will look slightly different on Windows vs on a Mac. The underlying functionality maybe the same but the way it looks may have subtle differences.

D. Payment gateway
Explanation:
e-commerce is a short for electronic commerce and it can be defined as a marketing strategy that deals with meeting the needs of consumers, by selling products or services to the consumers over the internet.
This ultimately implies that, e-commerce is strictly based on the buying and selling of goods or services electronically, over the internet or through a digital platform. Also, the payment for such goods or services are typically done over the internet such as online payment services.
A payment gateway can be defined as a merchant service technology used for the capturing, acceptance and transfer of digital payment from the bank account of a customer (buyer) to the bank account of the merchant (seller). Thus, payment gateway typically involves the use of credit or debit card for the payment of goods purchased or services provided.
In this scenario, a merchant bank and a merchant have been involved in a Web-based electronic transaction. Hence, a payment gateway mediates between the two i.e acts as an intermediary between the merchant bank and the merchant.
