If a speaker begins by saying, "It is nature’s best bug control, and night-blooming flowers depend on it for pollination. As North America’s most endangered animal, the Chiroptera, or ‘bat’, is in serious trouble," what type of introduction is he/she trying to use?
a. Quotation
b. Story
c. Personal reference
d. Create suspense

Option D, create suspense

Explanation:

In the beginning of the statement, the speaker has not mentioned the name of the natures best natural beg. He first described its extinguishing characteristics and then revealed its name “Chiroptera” and the problem “endangered species even being the best bug controller”  

A quotation is the direct representation of someone else’s statement, which is not the case here. Hence option A is not correct. It is also not a story with a plot.

Option C is also incorrect as personal reference based statement describes some personal happening, event or incident.

Hence, option D is correct
