Final answer:
The statement is false. Lady B is not considered the first DJ to play 'Planet Rock' on the radio. The correct option is b.
Step-by-step explanation:
The statement is false. Lady B is not considered to be the first DJ to play "Planet Rock" on the radio.
The first DJ to play "Planet Rock" on the radio was Afrika Bambaataa. He is widely recognized as a pioneer of hip hop music and culture, and his 1982 release of "Planet Rock" is considered one of the most important songs in the genre's history.
While Lady B, also known as Wendy Clark, is an influential DJ in her own right, she did not play "Planet Rock" on the radio for the first time.
Hence, Option b is correct.
