Which of the following statements is true about public goods?

(A) Public goods are non rival in nature.

(B) Public goods are non-excludable in nature.

(C) Public goods may be produced by the government or the private sector.

(D) Public goods and public production can be used interchangeably.

Choose the correct answer from the options given below:

Option 1 -> Statements (A), (B), and (C) are correct. Public goods are indeed non-rival (one person's use doesn't diminish another's) and non-excludable (cannot prevent people from using it). They can be produced by either government or private sector.

Option 2 -> Incorrect because statement (D) is false. Public goods and public production are not interchangeable concepts.

Option 3 -> Incorrect because statement (D) is false. Public goods refer to goods with specific characteristics (non-rival and non-excludable), while public production refers to government-produced goods regardless of their nature.

Option 4 -> Incorrect because it excludes statement (A) which is true, and includes statement (D) which is false.

Hence, Option 1: (A), (B) and (C) only -> Public goods have two defining characteristics: they are non-rival (consumption by one person doesn't reduce availability for others) and non-excludable (people cannot be prevented from using them). Examples include national defense, street lighting, and clean air. While governments often provide public goods due to market failure, private entities can also produce them (e.g., private parks, lighthouses). Statement (D) is false because public goods (defined by their characteristics) and public production (goods produced by government) are distinct concepts that cannot be used interchangeably. A government can produce private goods (like postal services), and private entities can produce public goods -> correct
