The correct answer is the oral stage. 

According to Freud's theory of psychosexual development, the oral stage refers to the first developmental stage that occurs from birth to 1 year of life. During this stage of psychosexual development, infants primarily communicate and explore the world through their mouths. Infants obtain pleasure from their mouth, tasting and sucking, and their behavior is thus geared to putting things in their mouth.
