Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Cumulatively.
- 'Cumulatively' means 'taken as a' whole' in combination'.

- The passage says that the attacks in combination are rising.
- Also between two verbs i.e. 'have' and 'been', only an adverb can be placed.
Hence, the chosen option is correct.
