According to the passage, ?

The correct answer is A) "online shopping needs the service of the internet" because online shopping fundamentally relies on internet connectivity to function. The entire process of browsing products, making selections, and completing purchases occurs through online platforms, which necessitates access to the internet. This digital infrastructure enables consumers to explore a vast array of products without the need for physical travel to stores.

In contrast, options B), C), and D) are incorrect because they do not accurately represent the nature of online shopping. Option B) suggests that online shops sell shopping carts, which is misleading; shopping carts in the online context refer to a software feature that facilitates product selection, not a physical product sold by these stores. Option C) implies that online shopping can only occur through banks, which is false, as numerous payment methods exist, including credit/debit cards and digital wallets. Lastly, option D) suggests that online shopping is conducted using cash, which is typically not the case, as it usually requires digital payments instead. Thus, option A correctly captures the essence of online shopping, highlighting its dependence on internet services.
