Under Sigmund Freud's Psychosexual Development Theory, what specific psychological conflict do boys and girls face in the 'Phallic Stage', and through which psychological process is the 'Electra Complex' developing during this stage primarily resolved according to Freud?

According to Sigmund Freud's psychosexual development theory, children in the 'Phallic Stage' (around 3 to 6 years of age) become aware of their genitals, during which the Oedipus and Electra complexes arise. Under the 'Electra complex', girls experience attraction towards the father and jealousy towards the mother, which the girl resolves by establishing identification with her mother and internalizing her role.
