Explanation

The correct answer is A) influenced by classical music because folk music is primarily characterized by its grassroots origins and cultural significance rather than formal musical traditions. Folk music typically arises from the everyday lives and experiences of common people and is often passed down orally through generations. This transmittal method allows it to retain its authenticity and connection to cultural identity.

In contrast, classical music is grounded in rigorous formal training, structured compositions, and theoretical frameworks. It is often performed by trained musicians in formal settings, which is distinct from the communal and informal nature of folk music. While folk music can incorporate various influences, its essence lies in its simplicity and relatability, making it accessible to everyone without the need for specialized education or practice.

Options B) transmitted orally, C) sung in groups or individually, and D) no regular practice is required, all reflect traditional characteristics of folk music, reinforcing the idea that folk music is distinct from more structured genres influenced by classical traditions.
