Which of the following is a disadvantage of using free-form slides?

A) They are limited to visual content
B) They require more time and creativity to develop
C) They are limited to textual content
D) They tend to distract the audience
E) They require animation software

Free-form slides require more creativity and time to develop because there are no set templates or guidelines, which can make it difficult to organize and structure information. This can also lead to inconsistent or confusing presentations. The other options are inaccurate, as free-form slides can include both visual and textual content, are not known to be particularly distracting, and do not require animation software (although it can enhance the presentation).
