How is the popularity trajectory of Rainey and Smith's songs described?

• A. They were widely popular from the start.
• B. They soared in popularity immediately.
• C. They gained popularity over time.
• D. They never achieved significant popularity.

Answer: (C)

Understanding how a popularity trajectory is described means looking at how interest changes over time. If the description says they gained popularity over time, that means the songs became more popular as time passed, showing a gradual upward trend rather than an instant hit. This fits scenarios where discovery and appreciation accumulate. The other possibilities would imply an immediate broad popularity, a rapid early surge, or consistently low popularity, none of which are indicated by the phrase. So the description best reflects a gradual rise in popularity.
