The correct answer is: A stone that goes on rolling gathers no moss.
The idiom “a rolling stone gathers no moss” means that someone who is always moving around and never stays in one place will not get attached to anything or anyone. This is because they are always changing and growing, and they do not have time to form lasting relationships or accumulate possessions.
The other options are incorrect because they do not convey the same meaning as the idiom. Option A, “collects,” means to gather or acquire something over time. Option B, “gets,” means to receive or obtain something. Option C, “gathers,” means to collect or assemble something. Option D, “accumulates,” means to amass or gather over time.
In the context of the idiom, “a rolling stone gathers no moss,” the word “gathers” is the most appropriate choice because it conveys the idea that the stone is constantly moving and never staying in one place. This is in contrast to the other options, which suggest that the stone is stationary and is able to collect or acquire things.
