Correct Answer: Accelerating growth of magnitude

Solution : The correct choice is the first option.

The expression a snowball effect is often used metaphorically to describe a situation where something starts small and then rapidly gains. When we say something has a "snowball effect", it means that a small initial change or event triggers a chain reaction, and the consequences or impact of that change grows increasingly significant or widespread over time.

Therefore, the correct meaning is, accelerating growth of magnitude.
