Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. has risen.
"has risen" is present perfect tense. The present perfect tense is used to describe an action that started in the past and continues to have an effect in present.
In this case, the population growth started in the past i.e. the last decade and its effect is still relevant today.
The correct sentence is- The population has risen very fast in the last decade.
