Hedy Lamarr is the actress who invented a technology that contributed to cell phone security. She developed frequency-hopping spread spectrum with George Antheil, a foundational tech for modern wireless communication.

Step-by-step explanation:

The actress who invented a piece of tech that later became part of cell phone security is B) Hedy Lamarr. Lamarr, in addition to her Hollywood fame, was a pioneering inventor and is perhaps best known for her contribution to the development of frequency-hopping spread spectrum technology. She and composer George Antheil developed this technology, which was originally designed to prevent the jamming of radio signals during World War II. The concept of frequency-hopping has since become a basis for modern wireless communication technology, including its use in securing cell phone communications.
