An extemporaneous speaker uses note cards because:
it's easier to conceal notecards than full sheets.

a. they are less likely to rip if the speaker is nervous.
b. a manuscript can get wrinkled and dog-eared.
c. there is potential for good audience contact.
d. he or she can present a speech without practicing.

It's D

Explanation:

Extemporaneous literally means to do something without practice. The speaker uses note cards so that they can say everything they're meaning to say, or planned on saying, without practicing the delivery. They just speak what they're reading on the cards. Hope this helps!
