Which of the following is characterized as an institution serving small savers?

Savings banks are specifically designed to serve the needs of small savers, making them the most appropriate choice in this context. Their primary function is to accept deposits from individuals and provide a secure opportunity for them to save money while earning interest. Savings banks typically focus on personal savings accounts, certificates of deposit, and similar products that cater to consumers looking for accessible and straightforward saving options.

In contrast, private equity firms primarily deal with investing in companies and generating returns for their investors rather than focusing on individual savers. Commercial banks, while they do offer saving accounts, also cater to larger businesses and corporate clients, which may lead them to prioritize larger transactions and clients with substantial financial needs. Mortgage companies primarily focus on providing home loans, which does not align with the mission of serving small savers.

As a result, savings banks hold a unique position in the financial landscape, directly addressing the needs of individuals looking to save small amounts of money securely and effectively over time.
