E.The honeybee’s stinger is heavily barbed and stays where it is inserted, with the result that the act of stinging causes

The correct option to this question is E (The honeybee’s stinger is heavily barbed and stays where it is inserted, with the result that the act of stinging causes)

Explanation:

This is the right answer because of Parallelism. A, C, and D are obviously wrong choices because of the use of "result in", which is not idiomatic in its use.

In option B, the word "with" was not used appropriately.

In Option C, using the "heavily barbed and staying..." does not align with the concept of parallelism.

Option D tries to single out only heavily barbed bees, while the sentence was generally emphasizing on honeybee's stinger.
