what multimedia element would enhance a speech about identifying bugs and insects?

Answer:
The 4th Option
Explanation:
This option is correct because it adds embellishment to the speech. The first option is too elementary. The second option is good, but lack color and won't bring anything exciting to the speech. The third option is just a series of symbols and it won't catch the attention of the listeners/viewers because they probably don't know what they mean.
Answer:
The other answer is incorrect. The second option is correct. :]
