The answer is letter A. Ann Sheridan was the person who was called the Oomph Girl. Born Clara Lou Sheridan on February 21, 1915, she started her career as a professional actress in 1934 after she won a beauty contest in 1932 which gave her the chance to have a small part in the Paramount film entitled “The Search for Beauty”. She starred in several films under Paramount, but her first lead only came in 1935 when she starred with Fred MacMurray in 1935.
She continued working under Paramount for the whole year until she signed a contract with Warner Bros. in 1936. She went with her new name “Lou Sheridan” and starred in small roles in films such as Sing Me a Love Song, San Quentin and Wine, Women and Horses until she moved into B pictures such as the film entitled Letter of Introduction in 1938. It was through this film that she became the Oomph Girl, a nickname she reportedly loathed.
