Which of the following is listed as a basic category of rock music in the material?

• A. Pop rock
• B. Heavy metal
• C. Grunge
• D. Ska

Answer: (A)

Pop rock is treated as a basic category because it sits at a broad, foundational level for classifying rock music, blending accessible pop melodies with rock instrumentation in a way that many artists fit into as a starting point. In the material, this broad, generic category is listed among the fundamental rock styles, whereas the other options are seen as more specific subgenres or crossovers that developed later or sit outside the core basic categories. Heavy metal is a distinct subgenre with a heavier sound, grunge is a particular movement within alternative rock from the 1990s, and ska originates from Caribbean music and only sometimes blends with rock. Because the question asks for what’s listed as a basic category, pop rock fits that broad, foundational role.
