Final answer:
c. Eleonor Roosevelt
Eleanor Roosevelt is credited with the quote about feeling inferior, while Abraham Maslow is renowned for his hierarchy of needs, and Guglielmo Marconi is recognized for the invention of the radio.
Step-by-step explanation:
The phrase "No one can make you feel inferior without your consent" is attributed to Eleanor Roosevelt. She was widely known for her role as a diplomat, humanitarian, and First Lady of the United States during President Franklin D. Roosevelt's four terms in office. This quote reflects her strong belief in personal self-esteem and empowerment.
As for the individual most well-known for proposing his hierarchy of needs, the answer is Abraham Maslow. Maslow's hierarchy is a psychological theory that prioritizes human needs from the most basic physiological needs to the higher-level self-actualization and self-transcendence needs.
In regards to the invention of the radio, credit is often attributed to Guglielmo Marconi. Marconi was an Italian inventor and electrical engineer who developed and patented the first successful long-distance wireless telegraph and in 1901 broadcast the first transatlantic radio signal.
