choices.text: savings:bonds bonds:treasury bonds listed company:securities company securities:liabilities
explanation: "stocks" are a type of "investment". investment methods include "savings" and "bonds", and "savings" and "bonds" are one category. "treasury bonds" are a form of "bonds". a "listed company" can be a "securities company", and a "securities company" can also be a "listed company", but it cannot be said that a "securities company" is a type of "listed company". "securities" is a collective term for various economic rights certificates, and also refers to special types of products. it is a legal certificate used to prove a certain kind of rights and interests enjoyed by the holders of the securities. "liabilities" refers to the formation of past transactions or events of the enterprise. it is expected that the current obligations of the enterprise will lead to the outflow of economic benefits, and there is no obvious logical relationship between "securities" and "liabilities".
